Title: 48÷2(9+3) = ? --> How smart are you?
Post by: spude on April 08, 2011, 07:44:17 AM
shouldn't be that difficult... however, 65% of stupid meatheads on another board had it wrong... i have high hopes for you fella getbiggers ;)

to make the situation similar than on that another board i'll give you two options...is the right answer 2 or 288?

I say 288, although the way you have it written without the multiplication sign is ambiguous so I am not surprised people think it's 2.

Annotation means    
48÷2 x (9+3) = ?

or

   
48÷2 x 12

or

24 x 12

or 288

It's not a math question per se - it's a question about understanding the notation

imagine two areas (2D) that are infinite on width but have limited height. Area A has 10cm of height and area B has 5cm, both have infinite width. The size of each area is infinite, but at ANY given point of the infinite axys A has the double the size of area B. Of course I was joking when I said "half" infinite but I hope you got the concept.

that is extremely clever, but it only works if you change the definition of infinite. a leats the definition i was using. infinite, if were talking spacial, has no bounds.

There are things called axioms, self evident truths you first accept. When you accept the axioms, you can construct theorems from them, i.e prove things.

No multiplication sign needed. Don't ask me how but I remember that from whatever grade that digits outside the parenthesis directs you to multiply. Just like "of" is used in word problems for multiplication and I think "is" is used for division...

This is correct, although I think it would be more clear if Spude hadn't typed out the equation in 1 line, so we can see if the (9+3) is in the numerator or the denominator.

If it's [48/2] (9+3), the answer's 288, but if it's 48/2(9+3), the answer's 2

It is 2.

You have to make the parentheses disappear before you proceed from left to right.

So even if division and multiplication have the same rank the multiplication of the number inside the parentheses must take place first.

Post by: jwb on April 08, 2011, 07:50:40 PM

The number inside the parentheses I refer to is the result of the addition of 9 and 3 which is of course the first step. ie 12.

The 12 must then be multiplied by the 2 BEFORE the division takes place to remove the parentheses.

The resulting number of 24 is then divided into 48 which gives us 2.
Title: Re: 48÷2(9+3) = ?
Post by: jwb on April 08, 2011, 08:00:24 PM
This guy explains it well on basically the same type of problem.

This next example displays an issue that almost never arises but, when it does, there seems to be no end to the arguing.

Simplify 16 ÷ 2[8 – 3(4 – 2)] + 1.
16 ÷ 2[8 – 3(4 – 2)] + 1
    = 16 ÷ 2[8 – 3(2)] + 1
    = 16 ÷ 2[8 – 6] + 1
    = 16 ÷ 2[2] + 1   (**)
    = 16 ÷ 4 + 1
    = 4 + 1
    = 5

The confusing part in the above calculation is how "16 divided by 2[2] + 1" (in the line marked with the double-star) becomes "16 divided by 4 + 1", instead of "8 times by 2 + 1". That's because, even though multiplication and division are at the same level (so the left-to-right rule should apply), parentheses outrank division, so the first 2 goes with the [2], rather than with the "16 divided by". That is, multiplication that is indicated by placement against parentheses (or brackets, etc) is "stronger" than "regular" multiplication. Typesetting the entire problem in a graphing calculator verifies this hierarchy:



Note that different software will process this differently; even different models of Texas Instruments graphing calculators will process this differently. In cases of ambiguity, be very careful of your parentheses, and make your meaning clear. The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations. But not all software is programmed this way, and sometimes teachers view things differently. If in doubt, ask!

No sir, you have to resolve 48÷2 first.

Let's see:

48÷2(9+3) is the same that (http://www.subeimagenes.com/thumb/ecuacion-31541.JPG) (sorry about the size of the image)

To multiply 2*(9+3) first,you have to put the equation like this:

48÷[2(9+3)]

I'm pretty sure this is the correct way.

Cmon bitches. PEMDAS. Except when there's multiplication or division in the problem you just do the one that comes first in the problem. Same goes with adding and subtracting, you do whichever operation comes first in the problem.

48÷2(9+3)  You have do parentheses first, so 48÷2(12). Then the division comes first, so you do 48÷2 so 24(12)= 288

For fucks sake. well sure, if you're assuming the expression reads 48/2 x (9+3) yes - that is definitely 24 x 12 which equals 288. but it's a trick question because of how it's typed out. i assume the expression reads 48/(2(9+3)) in which you calculate the bottom first, and then simplify, which is 48/24... obviously 2.

That is the thing.

Adding the 9 and 3 doesn't automatically get rid of the parentheses because there is a 2 waiting to multiply their sum.

You have to do that multiplication before proceeding.

Also, when do you see things in parentheses on the same line as the number they are going to eventually be divided into?

Implicit multiplication has a higher priority than explicit multiplication (or division). Some calculators, either handheld or web-based, follow this rule and others don't.

45÷2x is not evaluated as 45÷2*x just the same as 45÷2(9+3) is not the same as 45÷2*(9+3)

Next we'll see a ten page thread on how many hydrogen atoms are in a water molecule. Shit guys; if you failed to learn this in school, then look it up before you make an ass of yourself.
Obviously many people have only been taught PEMDAS since 48÷2(9+3) would almost always be written   48    in their exams.

I think you are missing the point good sir.  Classic algebra produces one answer and modern programming produces another.
No Sir. I get the debate. But algebra is absolute. Science is science and programming is only a means to an end.

to make the situation similar than on that another board i'll give you two options...is the right answer 2 or 288?

  Since the nine and three are between parenthesis, then they should be added first before dividing the number that comes before by the product of that addition. So the answer is four.

9+3=12......everyone can agree on that.

So the question is do you divide 48 by 2 before mulitplying by 12 or after?

Once you solve the parenthesis part it should look like 48÷2x12........in which case you work from left to right........48÷2=24 then x12=288

Even though multiplication and division are at the same level (so the left-to-right rule should apply), parentheses outrank division, so the 2 goes with the (12), rather than with the "48 divided by". That is, multiplication that is indicated by placement against parentheses is "stronger" than "regular" multiplication.

Incorrect.

You and nzmusclemonster are evaluating the expression as if it were a polynomial, which it's not. Division does not separate terms in this manner.

We basically have a constant expression, with two factors: 48/2 and 12.

Thus, in general, for any variables a, b and c, we would

Only this notation is correct:

_a_  =   _a_
bc         (bc)



However,

a/(bc) =   _a_
               bc

a/bc   =  a(c)
             b

yeilds two different quantities.



If you want to divide a series of terms, ex. ab, cd, ef :

it's written (ab) / (cd) / (ef)

or (ab) ÷ (cd) ÷ (ef)

or    ab
     _cd_
       ef


If you don't use parentheses, you violate left to right associativity, and will get an incorrect answer. It's that simple.

you would then get:

 ab / cd / ef   =     ((((a* b) /c) * d ) / e) * f


or  ab  ÷ cd ÷ ef  =  (((a *b) ÷ c) * d) ÷ e) * f

It yields a different quantity.




That's why, to get the answer of 2, you need parentheses :

 48÷(2(9+3))

It yields a different quantity.




That's why, to get the answer of 2, you need parentheses :

 48÷(2(9+3))



As stated numerous times the answer is indeed 2.

48/2(9+3)

The 2 above is a factor of (9+3). The (9+3) are the terms of 2. This statement written in English is:

Forty eight divided by twice the sum of nine plus three.

Also as mentioned before with the shorthand notation of 2(9+3) this can be in fact written many different ways, such as:

2(9+3) = 3(3+1) = (2*9+2*3) = (3*3+3*1) = (2*12) etc etc. The 2 is exclusive to whatever is inside the parenthesis. It is outside only to denote factored form. If I had an expression as:

(5+6+4)(8+9+7) this would imply:

(5*8+5*9+5*7+6*8+6*9+6*7+4*8+4*9+4*7)


With 48 / (5+6+4)(8+9+7) you wouldn't divide out the (5+6+4) by 48 THEN multiply the answer to the second set of parenthesis. The two together denote a single statement. They are 'factored' need to be simplified THEN can be calculated.

So with 48 / 2(9+3) we clearly see this:

Operand = 48
Operator = / <--- which is also a fraction bar
Operand 2(9+3) = (2*9+2*3)=(2*12) = etc etc

2(9+3) simplified using the Distributive property of multiplication over addition shows that 2(9+3) = (2*9+2*3). The two is inside the parenthesis the entire time. Only reason it's outside is for factored form purposes.
Yes that's correct, just because you see the number '2' outside does not mean it's an operand by itself. It's notation for being directly next to the parenthesis means it was factored 'out' and is in fact part of the statement inside the parenthesis which we just saw.

So following algebra rules of simplifying, distributive property, factored form and then FINALLY your order of operation you end up with:

48 / 2(9+3) <---- remember this is one statement. 2 factored out and belongs inside according to Dist. property.

48 / (2*12) or (2*9+2*3) or 24
48 / 24 = 2.

Lastly calculators are meant to work from left to right NO MATTER WHAT. Whatever you put inside it's intention is to work left to right. No corollaries, theorems, principles, properties etc. etc. After a certain level of math you are free to use calculators in tests simply because they have limits. Be very careful when relying on internet calculators.

OR,

This question has certainly created some controversy as to whether or not this is either 2 or 288. There seems to be confusion between the order of operation, distributive property, precedence of multiplication over division etc etc.

Some have cited online calculators, their home calculators or recited the mnemonic PEMDAS.
I'll show you here how you can indeed use those to check your answer.

The main question is does the 48 get divided by 2 and then multiply (9+3) or is the 2(9+3) a single statement and uses a property of distribution?

I provided several variations with proofs but many insisted that Google and other online calculators can never fail us so yes we will use our trusty online calculators to finally close the book on this expression.

We'll do a simple way to check our work using variables.

Set the 2 in the equation to the variable x and rewrite the expression as an equation now:
48 / x(9+3) = 2

Rewriting the equation this way will help us check the answer of 2 in the original problem.

Now let's go ahead and continue to simplify this.
48 / (x*9+x*3) = 2

Which leaves us with 48 / 12x = 2

Now that we made it this far there should be NO QUESTION as to what is going on here. We have now:

48 / 12x = 2

Let's continue to simplify and make things easier for everyone shall we? 48 / 12x, well 48 divides amongst 12 a total of 4 times so we can reduce this fraction to 4 / x. Did we all see how this was done?

So now we are left with 4 / x = 2

With me so far?

Now that you've gotten this far we have a reduced, easy, clean, neat and straightforward equation. Go ahead and type:

4 / x = 2

in any online calculator or solve this with good ole fashioned pencil and paper.

What does everyone end up with?

Does x = 2?

AND IF YOU BELIEVE I WROTE THE ABOVE OR MOST OF WHAT I HAVE POSTED I HAVE SWAMP LAND TO SELL YOU ;)

IT IS INTERESTING HOW IF YOU INPUT 48÷2(9+3) INTO THIS CALCULATOR IT SAYS 2 BUT IF YOU INPUT 48/2(9+3) IT SAYS 288.

you called everyone idiots because you think they dont know that parenthesis need to be solved first. almost every single person in the thread knows that.

the confusion lies in whether or not you multiply first. or divide first.  

the problem equals 2 if you follow the rules of algebra precisely, pemdas left to right.

Falcon,

Is this what you went through for your PhD in calculus?

Prerequisites
 
The Department of Mathematics offers 2 PhD degrees, one in Mathematics and one in Applied Mathematics. Applicants for admission to either PhD program are expected to have preparation comparable to the undergraduate major at Berkeley in Mathematics or in Applied Mathematics. These majors consist of 2 full years of lower-division work (covering calculus, linear algebra, differential equations, and multivariable calculus), followed by 8 one-semester courses including real analysis, complex analysis, abstract algebra, and linear algebra. These eight courses may include some mathematically based courses in other departments, e.g., physics, engineering, computer science, or economics.
 
Applicants for admission are considered by the Department's Graduate Admissions and Appointments Committees. The number of students that can be admitted each year is determined by the Graduate Division and by departmental resources. In making admissions decisions, the Committee considers, among other things, grades in mathematics courses, level of mathematical preparation, letters of recommendation, and GRE scores.
 
Experience has shown that the score on the Mathematics Subject GRE is a partial indicator of preparation for Berkeley's PhD program. A score below the 80th percentile suggests inadequate preparation and must be balanced by other evidence if a favorable admission decision is to be reached.
 
Degree Requirements
 
In outline, to qualify for the PhD in either Mathematics or Applied Mathematics, the candidate must meet the following requirements.
 
1.During the first year in the PhD program:
 
a.take at least 4 courses, 2 or more of which are graduate courses in mathematics;
 

b.and pass the six-hour written Preliminary Examination covering primarily undergraduate material. (The exam is given just before the beginning of each semester, and the student must pass it within their first 3 semesters.)
 


2.Pass a three-hour, oral Qualifying Examination emphasizing, but not exclusively restricted to, the area of specialization. The Qualifying Examination must be attempted within two years of entering the program.
 

3.Complete a seminar, giving a talk of at least one hour duration.
 

4.Pass one language examination in French, German, or Russian.
 

5.Write a dissertation embodying the results of original research and acceptable to a properly constituted dissertation committee.
 

6.Meet the University residence requirement of two years or four semesters.
 

The detailed regulations of the PhD program are as follows:
 
Course Requirements

During the first year in the PhD. program, the student must enroll in at least 4 courses. At least 2 of these must be graduate courses in mathematics. Exceptions can be granted by the student's Graduate Advisor.

Preliminary Examination
 
The Preliminary Examination consists of 6 hours of written work given over a two-day period. Most of the examination covers material, mainly in analysis and algebra, that should be part of a well-prepared student's undergraduate training. The Preliminary Examination is offered twice a year---during the week before classes start in both the Fall and Spring Semesters. A student may repeat the examination twice. A student who does not pass the Preliminary Examination within 13 months of the date of entry into the PhD program will not be permitted to remain in the program past the third semester. In exceptional cases, a fourth try may be granted upon appeal to Committee Omega.
 
Qualifying Examination
 
To arrange for the Qualifying Examination, a student must first settle on an area of concentration, and a prospective Dissertation Supervisor, someone who agrees to supervise the dissertation if the examination is passed. With the aid of the prospective supervisor, the student forms an examination committee of 4 members, at least 2 of which must be members of the Department. The Graduate Division requires that at least one committee member be from outside the Department and that the committee chair be someone other than the Dissertation Supervisor. The syllabus of the examination is to be worked out jointly by the committee and the student, but before final approval it is to be circulated to all faculty members of the appropriate Sections. The Qualifying Examination must cover material falling in at least 3 subject areas and these must be listed on the application to take the examination. Moreover, the material covered must fall within more than one Section of the Department. Sample syllabi can be seen in 910 Evans Hall.
 
Before attempting the Qualifying Examination, the student must pass one language examination. The student must attempt the Qualifying Examination within twenty-five months of entering the PhD program. If a student does not pass on the first attempt, then, on the recommendation of the student's examining committee, and subject to the approval of the Graduate Division, the student may repeat the examination once. The examining committee must be the same, and the re-examination must be held within thirty months of the student's entrance into the PhD program.
 
For a student to pass the Qualifying Examination, at least one identified member of the subject area group must be willing to accept the candidate as a dissertation student, if asked. The student must obtain an official Dissertation Supervisor within one semester after passing the Qualifying Examination or leave the PhD program. For more detailed rules and advice concerning the Qualifying Examination, consult the Graduate Assistant in Room 910 Evans Hall.

You do realize that by the way you typed it in there it is going to multiply the parenthesis by 1 right? I am horrible at math and always made average grades in math and still know this.

yup answer is 2

as stated earlier Please excuse my dear aunt sally...

m = multiplication, d = division

notice how m comes before d...

so after the P which stands for parenthesis your left with 48/2 x 12

what comes first again class? M or D?

M so you multiply first...giving us 48/24 which equals 2...

youre notation is a tad misleading to get 288 you need (48/2)(9+3)...

Only this notation is correct:

_a_  =   _a_
bc         (bc)



However,

a/(bc) =   _a_
               bc

a/bc   =  a(c)
             b

yeilds two different quantities.


That's why, to get the answer of 2, you need parentheses :

 48÷(2(9+3))

This is what I said earlier

This is correct, although I think it would be more clear if Spude hadn't typed out the equation in 1 line, so we can see if the (9+3) is in the numerator or the denominator.

If it's [48/2] (9+3), the answer's 288, but if it's 48/2(9+3), the answer's 2

If you write it out on paper, there would be no confusion, since it would appear as one of the 2 equations below, depending on which the answer will be 288 or 2. But when you type it out in 1 line, it's confusing, esp. since people are sloppy with things like spacing

  Kiwi, there is no confusion. What you have just wrote are two completely different mathematical expressions, hence the different answers. The notation in mathematics is precise. The parenthesis is there to indicate that the items between it should be computed with each other before being computed with the rest of the expression. There is no other possibility since mathematical notation is an internationally established norm.

the problem equals 288 if you follow the rules of algebra precisely, pemdas left to right. 

but if you just follow pemdas, then you get two answers. either 2 or 288.

  Quite your sarcasm, idiot, because you are looking even more foolish than you already are. The problem does not equal 288 in any way, shape or form. There is only one answer and that is two. You cannot compute the equation before adding the numbers between parenthesis, so there is only one answer. Stop acting like you had me there, because you didn't. Who gives a shit about programming language? This is mathematical expression and the rules of mathematical notation apply and no other, you fucking dumbass.

You keep bringing up how the computing of the numbers within the brackets should be done first, but nobody's arguing that point. And in both the equations I've written out, the addition within the brackets does gets solved first before multiplying it with 2 or 24.

The point I'm trying to make is that both the equations I've posted will read 48÷2(9+3) when typed out on a single line as in the original post.

the reason why it is two is because multiplication and division have equal priority in simplifying expressions, and thus you have to work from left to right, with the division happening before the multiplication, but after the addition that was done in the parenthesis.

the 2 main reminders of the sequence to this equation is pemdas and bedmas, notice how in one the d is before the m and the other one the m is before the d, this is because it doesn't matter if division is done first or multiplication is done first as long as either or both ar done before adding or subtracting, hence you have to follow from left to right always. But the brackets are what are confusing people not the order.

If one strictly uses the standard order of operations to solve mathematical expressions, the answer to the problem would be 288, which is also the same solution provided by WolframAlpha and Google.


If one uses multiplication before division (PEMDAS being especially popular in the United States), the problem would be solved like this:
48 ÷ 2 * (9+3)=
48 ÷ 2 * (12)=
48 ÷ 2 * 12=
48 ÷ 24=
2
However, solving the problem like this would be considered erroneous because multiplication and division hold equal precedence.
Some sources maintain that multiplication does not always comes before division:

- University of North Texas
- Northern Michigan University
- Deb Russell
- University of Minnesota Rochester
- Midland College
- Hofstra University

The problem everybody here is making is thinking that (9+3) is attached to only the 2 in front of the bracket, when in fact it is attached to the 48 and the 2 and if you had 48 divided by 2 times 4 divided by 2 then whats in the brackets is attached to the result of the 48 the 2, the 4, and the 2. The brackets is attached to the result of all numbers preceding it not just the immediate number preceding it in this case. so you can read the question in this manner 48 times 12 divided by 2 or 48 divided by 2 times 12, c mon guys this is grade 9 math :o

the one on the left uses '/' for division, which indicated everything to the right of it is divided by what is to the left of it. 

the one on the right uses a standard division sign which does not mean the whole right side must be divided.

exactly, that particular calculator is reading that everything after the sign/ is dividing including what is in the brackets. the other calculator is dividing 48 by 2 only.

This doesn't apply to PEMDAS for this equation since there are no radicals but it is food for thought as to whether teachers should just be teaching the correct order of operations and not a learning crutch.

PEMDAS: Terminate With Extreme Prejudice
Wednesday night, I walk into a lecture room for my first evening algebra class of the spring. And what do I see on the chalkboard? Some guy has oh-so-carefully written out the PEMDAS acronym, with each associated word in a column sequence. In fact, that's the only thing he's got on the board after a presumably 2-hour lecture.

So, now it's time for my official AngryMath "Kill the Shit Out of PEMDAS" blog posting.

It's a funny thing, because I'd never heard of the PEMDAS acronym until I started teaching community college math. None of my friends had ever heard of it; artists, writers, engineers, what-have-you, from Maine or Massachusetts or Indiana or France or anywhere. But for some reason these urban schools teach it as a memory-assisted crutch for sort of getting the order of operations about halfway-right (PEMDAS: Parentheses, Exponents, Multiplying, Division, Addition, Subtraction.)

But the problem is, it's only half-right and the other half is just flat-out wrong. Wikipedia puts it like this ( http://en.wikipedia.org/wiki/Order_of_operations ):

In the United States, the acronym PEMDAS... is used as a mnemonic, sometimes expressed as the sentence 'Please Excuse My Dear Aunt Sally' or one of many other variations. Many such acronyms exist in other English speaking countries, where Parentheses may be called Brackets, and Exponentiation may be called Indices or Powers... However, all these mnemonics are misleading if the user is not aware that multiplication and division are of equal precedence, as are addition and subtraction. Using any of the above rules in the order addition first, subtraction afterward would give the wrong answer..."

In my experience, none of the students who learn PEMDAS are aware of the equal-precedence (ties) between the inverse operations of multiplication/division and addition/subtraction. Therefore, they will always get computations wrong when that is at issue. (Maybe prior instructors managed to scrupulously avoid exercises where that cropped up, but I'm not sure how exactly.)

Here's a proper order of operations table for an introductory algebra class. I've taken to repeatedly copying this onto the board almost every night because it's so important, and the PEMDAS has caused so much prior brain damage:

1. Parentheses
2. Exponents & Radicals
3. Multiplication & Division
4. Addition & Subtraction

Notice that each operation (after parentheses) is linked with the exact opposite (inverse) in equal precedence. Of course, you have to emphasize that (a) "parentheses" means "stuff inside the parentheses", and (b) in each stage you'll go left-to-right in the expression doing either the operation or its inverse in any order. In contrast, PEMDAS gets parentheses right (and that's pretty much it); but among its flaws are (1) leaving out radicals as the inverse of exponents, (2) overlooking that multiplication & division are tied, and (3) overlooking that addition & subtraction are tied.

An example I use in class: Simplify 24/3*2. Correct answer: 16 (24/3*2 = 8*2 = 16, left-to-right). Frequently-seen incorrect answer: 4 (24/3*2 = 24/6 = 4, following the faulty PEMDAS implication that multiplying is always done before division).

If you're looking at PEMDAS and not the properly-linked 4-stage order of operations, you miss out on all of the following skills:

(1) You solve an equation by applying inverse operations (i.e., cleaning up one side until you've isolated a variable). If you don't know what operation inverts (cancels) another, then you'll be out of luck, especially with regards to exponents and radicals. Otherwise known as "the re-balancing trick", or in Arabic, "al-jabr".

(2) Operations on powers all follow a downshift-one-operation shortcut. Examples: (x^2)^3 = x^6 (exp->mul), sqrt(x^6)=x^3 (rad->div), x^2*x^3 = x^5 (mul->add), x^5/x^3 = x^2 (div->sub), 3x^2 +5x^2 = 8x^2 (considering a shift below add/sub to be "no operation"). If you don't see that, then you've got to memorize what looks like an overwhelming tome of miscellaneous exponent rules. (And from experience: No one succeeds in doing so.)

(3) Distribution works with any operation applied to an operation one step below. Examples: (x^2*y^3)^2 = x^4*y^6 (exp across mul), (x^2/y^3)^2 = x^4/y^6 (exp across div), 3(x+y) = 3x+3y (mul across add), sqrt(x^2*y^6) = x*y^3 (rad across mul), etc. However, the following cannot be simplified by distribution and are common traps on tests: (x^3+y^3)^2 (exp across add), sqrt(x^6-y^6) (rad across sub), etc.

(4) All commutative operations are on the left, all non-commutative operations are on the right (the way I draw it). Also, any commutative operation applied to zero results in the identity of the operation immediately below it. Examples: x^0 = 1 (the multiplicative identity), x*0 = 0 (the additive identity), x+0 = x (no operation), etc. The first example is usually forgotten/done wrong by introductory algebra students.

(5) The fact that each inverse operation generates a new set of numbers (somewhat historically speaking). Examples: Start with basic counting (the whole numbers). (a) Subtraction generates negatives (the set of integers). (b) Division generates fractions (the set of rationals). (c) Radicals generate roots (part of the greater set of reals).

(6) Finally, per my good friend John S., perhaps the most important oversight of all is that PEMDAS misses the whole big idea of the order of operations: "More powerful operations are done before less powerful operations". I write that on the board, Day 1, even before I present the basic OOP table. It's not a bunch of random disassociated rules, it's one big idea with pretty obvious after-effects. (See John's MySpace blog.)

So as you can see, PEMDAS is like a plague o'er the land, a band of Vandals burning and pillaging students' cultivated abilities to compute, solve equations, simplify powers, and see connections between different operations and sets of numbers. If you see PEMDAS, consider it armed and dangerous. Shoot to kill.

the reason why it is two is because multiplication and division have equal priority in simplifying expressions, and thus you have to work from left to right, with the division happening before the multiplication, but after the addition that was done in the parenthesis.

Everyone needs to take a deep breath.

We can all agree that 48÷2(9+3) is a lousy way to ask this question.

From reading around some more I have found out that people have been taught two different conventions.

And these different conventions affect what you think you are being asked by 48÷2(9+3)

To the PEMDAS crowd a/bc is the same as a/b*c

To the other crowd a/bc is the same as a/(bc) since bc is not the same as b*c at least to them.

Why have conventions changed and therefore older calculators give 2 and newer ones give 288?

It appears teachers didn't think kids were bright enough to remember the correct order of operations which is

1. Parentheses
2. Exponents and Radicals
3. Multiplication and Division
4. Addition and Subtraction

and wanted to use PEMDAS even though it leaves out radicals and doesn't make it clear to all about equal weighting of MD and AS.

The simple fact is there is no way that half of all the millions of people debating this online are doing WHAT THEY WERE TAUGHT incorrectly.

so what is the answer? what is the question?

Ha! Ha! Touche my friend, touche! In studying mathematics the "÷" is so seldom used (I don't even have the symbol on my lap top and had to copy and paste it from the original post). The "/" symbol for division is so ingrained in me that even when I see "÷" I still think "/". That's why I copied it that way. I doubt it would ever be written as it written in the original post in real life. My windows calc also doesn't have the "÷" symbol.

48÷2(9+3) IS THE SAME AS 48÷2X(9+3) WHICH IS THE SAME AS 48   1  (9+3):
                                                                                                   ---X--X-------
                                                                                                    1    2     1

48X1X(9+3)     48X12    576
-------------- = ------- =  ----  = 288
 1X2X1                 2         2

WE CANNOT ASSUME WE MUST MULTIPLY THE 2 WITH THE (9+3) FIRST BECAUSE WE ARE DEALING WITH MATH.. ITS EITHER BLACK OR WHITE...WRONG OR RIGHT WE HAVE TO CALCULATE THE PROBLEM EXACTLY THE WAY IT IS GIVEN...FOR THE ANSWER TO BE 2 IT MUST READ 48÷[2(9+3)] AND BASED ON ORDER OF OPERATIONS WHATS IN THE BRACKET MUST BE CALCULATED FIRST BUT SINCE THE PROBLEM WAS NOT WRITTEN THAT WAY PROPERS ORDER OF OPERATIONS MUST BE FOLLOWED AND THE ANSWER IS UNDENIABLY 288

To people it was taught to 48/2(9+3) is not the same as 48/2*(9+3) but it is now considered the same.

Does that affect the answer? No it doesn't provided you fit the question to the convention.

A big part of it is that the vertical format was used and not the horizontal format you see more of today because of computers.

With the new convention the question as seen by people of the old convention in (horizontal format) was as you pointed out 48/(2(9+3)) but that simply contains too many parentheses to be practical so they made ab the same as a*b and changed the question format to match.

The Algebra is the same it can't change.

Post by: jwb on April 12, 2011, 06:51:33 PM
This guy explains it well...

The practical effect is that you should never write an expression like  1/2x unless you are sure it won't generate any confusion -- e.g. if you can be certain your audience will infer from context whether you mean  (1/2)x or 1/(2x) .

Sometimes, you will face an author/teacher who uses the standard convention. If you prefer a different convention, then you're going to have to learn to read the wrong convention, and avoid writing anything that would be different amongst the two conventions.

The same advice applies to someone who prefers the standard convention, but is faced with a book/teacher that uses a different one.

Read this...

Mathematics is supposed to provide you with single, definitive answers. However, in this case, it does not. I really scoured the internet and countless textbooks for the proper answer and have made inquiries with few people I know whom I venerate as some of the greatest minds that I have had the luxury of meeting and the answer isn't as definitive as you would hope. Sadly, the real answer is that both sides are correct to a point. (…and it pains me to even remotely admit that anything outside of 288 could be the answer).

Position 1: The Order of Operations: This stance states that since the standard order of operations puts multiplication and division on the same rank, the equation can be read as (48÷2)*(9+3). This reigns with truth as 48÷2(9+3) is the same as 48÷2*(9+3). Using the standardized left-to-right notation, the answer can be nothing outside of 288. This left-to-right concept is indicative of “PEMDAS” that we all learned in grade school.

Position 2: The Distributive Property: This stance states that multiplication through juxtaposition, being a commonplace concept, naturally makes a parenthetical implication around grouped numbers. Thus, the equation appears as 48÷[2(9+3)]. This technique is correct as well. However, this makes the answer 2.

If you are bored enough to read [reference 1], you’ll see that the writer has noted multiplication by juxtaposition as being used in algebraic nomenclature dating as far back as the fifteenth century. That being said, the standard left-to-right order of operations predates even that. The real problem is that both techniques are taught in our school systems, depending on the chosen literature. Both forms can be found dating far enough back that there’s a solid argument for either chosen notation. Sadly, there is no current ‘authority’ to standardize which is appropriate. As Doctor Peterson mentions in [reference 2] “When algebraic notation was first being developed, it was common for each writer to begin by explaining his own notation.” That seems to still be true as students are still being taught the distributive property and multiplication by juxtaposition as well as the standardized left-to-right order of operations. The correct answer breaks down to who is asking the question.

As much as you’d like it to be a single definitive answer, alas, it is not. In my opinion, that needs to change. Someone should standardize it. But the real answer here, to end all further questions on this topic, is the ambiguity of the formula makes it faulty to begin with. No self respecting mathematician would have used this notation. Formula ambiguity can destroy the outcome. This should have been written as 48 / (2 * (9+3)) or (48 / 2)*(9+3), thus guaranteeing the desired result.

To summarize, as much as one would like to claim one answer or the other, the sad reality is; being as there is no current standardization in this case, the answer is relative to the inquirer. In the future, if an “ab/cd” –type equation is proposed, you’re better off inquiring as to the proposer’s notation preference.

and thats besides the fact that the advanced positions which require high level math are really not necessary but luxury compnents to society anyways. we'd probably be better off with out them.

Just go shoot yourself  ::)

LUXURY COMPONENTS?? What the in the blue fuck do you think you're typing on right now?? A hint: it would not have been there in front of you if it wasn't for advanced mathematics. Most of modern society was constructed with the aid of complex mathematics. Mathematics is essential for the world you have come to known. It's a good thing you do not actively participate in constructing it. Just stay away. Smoke your pot and let people with a shred of common sense do their thing.

Damn you are RETARDED! and you don't even realize it. You only need geometry for the bridge? lol. I'm studing "**** engineering" and we use integration mainly to calculate fluid presion and work. It's very important to us and we are far from being "rocket scientists". Saying advance algebra is a complete waste of time it's just so retarded that I don't know if you are a troll or what.

mathematics is ok up to basic algerba and geometry plus statistics.. advanced algebra and above is a complete waste of time for 99% of people..


my sister works at and lives next to UC merced so that is where i am going. plan to study economics and then business. my associate degree is in geography.

You're going to study economics and you don't think advanced mathematics aren't useful? Are you fucking retarded? Anything beyond the two introductory macro and micro classes you'll take usually starts involving calculus and other concepts. A number of the world's best economists were math majors and some of the most influential economics concepts taught today were created by mathematicians (i.e. John Nash).

But you go ahead and say maths isn't needed if it helps you sleep at night.

true. as a business school student i can say economics is probably the most mathematic major in our school...my own major is strategic management which is probably as far from math as possible but i've also taken courses in both economics, accounting and finance and work now as a sales manager so trust me, i know what i'm saying...

Sure from that perspective. Other than food, a blanket and a grass hut virtually everything you and I have are luxuries. One to the things that separates us from animals is how we can improve the qualities of out life. Refrigeration, a/c, houses of all shapes and sizes, running water, toilets, plumbing, varieties of foods, spices, seasonings and ways to prepare it, gyms, your weed, hair cuts/styles, books, movies..., it just goes on and on and on. We've evolved so that our lives doesn't just consist of just looking for food, avoid being eaten, and finding somewhere not to get wet or sun burn.

Tbombz, your level of ignorance and stupidity is so mind boggling that you are simply unaware of all that's out there and the difference that it makes and just don't have the imagination and sense of self-awareness to realize how stupid you really are. That's why you feel so arrogantly and smugly comfortable spouting off on subjects you just have no clue about and are oblivious to how you come across and how no one takes you seriously or respects you. You're just a sad joke still living with his parents getting high, trying to get big lifting weights and having gay sex with no concrete plans for the future.

LMFAO dizzle mathematics is the language of life my boy...everything can be boiled down to math.

If youre going to study economics you are indeed going to have to learn a good amount of calculus and stats. If you go into accounting youre going to have to learn a whole shit load of accounting related equations and formulas(other words for math ;)) Finance is again a lot of statistics and calculus.

if you go into something where you need a license like the Series 7 you cant use a calculator the GMATS dont allow you to use a calculator.

I agree its stupid but it also is very important to understand the concepts behind the calculations the calculators do. It allows you to manipulate and combine equations, formulas, problem solving techniques in your head.

Rule 1:     First perform any calculations inside parentheses.
Rule 2:     Next perform all multiplications and divisions, working from left to right.
Rule 3:     Lastly, perform all additions and subtractions, working from left to right. - Mathgoodies.com

PE(MD)(AS)- The reason (multiplication & division - MD) and (add & subtract - AS) are "grouped" in sets of parentheses is that when those operations are next to each other you do the math from left to right.  You do not always do multiplication or addition first.  It may be the case where division will be done BEFORE multiplication or subtraction will be done BEFORE addition - Regentsprep.org

A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". This tells you the ranks of the operations: Parentheses outrank exponents, which outrank multiplication and division (but multiplication and division are at the same rank), and these two outrank addition and subtraction (which are together on the bottom rank). When you have a bunch of operations of the same rank, you just operate from left to right. For instance, 15 ÷ 3 × 4 is not 15 ÷ 12, but is rather 5 × 4, because, going from left to right, you get to the division first. - Purplemath.com

Rules

1. Calculations must be done from left to right.

2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.

3. Exponents (or radicals) must be done next.

4. Multiply and divide in the order the operations occur.

5. Add and subtract in the order the operations occur. - Math.About.com

maybe but most of you fellas have understood it wrong...this ugmt dude on the other hand did a good job explaining it out for all the less intelligent getbiggers...pe(md)(as) is actually a very good and easily understandable way to write it...multiplication and division are same level operations that are performed left to right, same with addition and subtraction...techncally we can't even separate multiplication and division from each other, multiplying by two is the same as dividing by 1/2 and so forth...and adding 3 is exactly the same operation as subtracting -3

I agree.

"multiplication and division are done as they are encountered from left to right."

No, I'm not familiar with that term.

ab is shorthand for a * b, that is all what "implicit" multiplication is - shorthand notation. It does not grant higher precedence than it already has. Parentheses do that.
