48÷2(9+3) = ? --> How smart are you?

[sync pulse]

I guess the most widely used spreadsheet program in the world doesn't know order of operations

You are confusing programming languages with math notation...they are not the same but have many of the same symbols...spreadsheets are rooted in "Dartmouth Basic"

288.

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.

[jwb]

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.

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 (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.

[WhiteCastle]

x=9+3.

48 ÷ 2x
(48)(1/2)(1/x)
48/2x
48(9+3)
48(9+4y)
12(1.45 +1/34x + 5y)
9-7
2

EOT.

[Doug_Steele]

x=9+3.

48 ÷ 2x
(48)(1/2)(1/x)
48/2x
48(9+3)
48(9+4y)
12(1.45 +1/34x + 5y)
9-7
2

EOT.

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

It's 2 for christsake.

i'm back bitches! it's fuckin' 288...i was the second best graduate in my college in europe, now studying economics in university and this is fucking simple...you first count what's inside parenthesis then, because multiplication and division are same level operations, go from left to right...got it?

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.

here is a question: how many dumbass Getbig users does it take to screw in a lightbulb?

(48 ÷ 2) * (9 + 3) = 288

you don't need to fuckin'g assume anything!! just count it as it's written, it's written to a bit unusual but, nevertheless, mathematically sound form..this would be an easier way to write it ...there's simple rules about the order of operations that give you only one option....and the asnwer is 288

[g101]

the answer is 288 ...

[spude]

the answer is 288 ...

BINGO!!!

I just wonder why this is so hard for people to understand.

GUYS IT'S NOT HARD ILL PUT IT AGAIN IN EASY TERMS

Did you study calculus and statistics as part of your university degree?

Sit the fuck down chump.

The answer is 2.

You are embarrassing yourself.....

The way you do it you are changing the entire way the equation is written out.

Don't over think it.

Do it as it is written without changing the format and the answer is 2.

It is very basic, but everyone it trying to complicate it.

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?

It would be written         48        in most exams.
                                 2(9+3)
     

                       
                               

[nzmusclemonster]

Food for thought  

48 ÷ x(9 + 3) = 288
48 ÷ 9x + 3x = 288
48/12x = 288
4/x = 288
4 = 288x
4/288 = x
1/72 = x
