48÷2(9+3) = ? --> How smart are you?

[Primemuscle]

Type the exact question into mathway and see what happens.... 48÷2(9+3)

Yep, the answer from Mathway is 2 when you enter the problem in this manner.

[tonymctones]

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)...

hope this helps

[tonymctones]

LMAO this is a self ownage thread for the OP

[Primemuscle]

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.

Actually, I typed it in as 48/2(9+3)=X. Mathway converted what I typed and expressed it as it appears in the pasted page from Mathway.

[tonymctones]

^^^^

thats because it interpreted it as 48/2 x 9+3

not 48/2(9+3) which is how the original question is set up.

in the first one the 9+3 isnt in the denominator in the second one it is...

So whoever programmed it thinks ÷ is different from / in a horizontal format.

Only like 20% of getbiggers can do enough math to balance their checkbook anyway... this is far too much information for this place.

show some respect to Suckmymuscle!

if he has trouble solving a problem, it's not b/c he made an error but b/c there's an error in the problem itself

[kiwiol]

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

  What are you talking about? The only error I made was not seeing the two multiplying the sum there and I recognized that. Did I make any error in how I solved the mathematical expression? No.

  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.

SUCKMYMUSCLE

[suckmymuscle]

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.

  But how does that change anything? The numbers between parenthesis will be computed first always. So the answer is always 2. It never gets to 288.

SUCKMYMUSCLE

48/2(9+3)
48/2(12)
24(12)
288

[tbombz]

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.

[nzmusclemonster]

48/2(9+3)
48/2(12)
24(12)
288

Wrong.... There is no need to change how it is written.

tbottom is embarrassing himself.

[JOCKTHEGLIDE]

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?

congrats you made a thread,,,that will carry on for 15 pages,,,of pointless stupid bickering that no one gives a shit about only those who have nothing else to do except not fck their supermodel wives, not care about the 1 millions they gained in stock, nothing else better do cause we are so super rich, too many cars to drive so we dont drive, too many homes to live in so we live in the basement somewhere,,,,,so we instead sit here try to solve a pointless problem on math that does not not benefit society or ourselves 

[tbombz]

i didnt change how it was written

[the Algebra Wizard]

i come to this board to escape work, not to do it !!!! 


the correct solution is 2 !!!!!

Algebra Wizard Approved

[FREAKgeek]

jwb, look up the definition of a polynomial. Note polynomial form.

Why is it that you can't use division to separate terms?

I'll give you a hint. Parentheses would look ugly.

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)...

hope this helps

This.......


 ......is correct  and best describes how i and most others got 2.

[OTHstrong]

This.......


 ......is correct  and best describes how i and most others got 2.

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.
