48÷2(9+3) = ? --> How smart are you?

[Cornelius Funk]

How the hell does this topic get to 7 pages? Seriously? Mathematics is a science. There are steadfast rules. It's not BB judging. 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.

I think you are missing the point good sir.  Classic algebra produces one answer and modern programming produces another.

Obviously many people have only been taught PEMDAS since 48÷2(9+3) would almost always be written   48    in their exams.

No Sir. I get the debate. But algebra is absolute. Science is science and programming is only a means to an end.

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?

  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.

forty eight divided by two times nine plus three
forty eight divided by two times twelve.
forty eight divided by twenty four.
two.


forty eight divided by two times nine plus three.
forty eight divided by two times twelve.
twenty four times twelve.
two hundred and eighty eight.

This should be good for a laugh..............write it out and explain how your 160+ iq came up with 4.

  I'm sorry. I didn't see the two there.

  In any case, the answer is two and not two hundred and eighty eight since the 9 and 3 are between parenthesis and thus should be added together before multiplying the terms by two.

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.



http://en.wikipedia.org/wiki/Order_of_operations :

Similarly, care must be exercised when using the slash ('/') symbol. The string of characters "1/2x" is interpreted by the above conventions as (1/2)x. The contrary interpretation should be written explicitly as 1/(2x). Again, the use of brackets will clarify the meaning and should be used if there is any chance of misinterpretation

Do we believe wiki or the American Maths Society?

The convention used by the Mathematical Reviews of the American Mathematical Society (AMS), Mathematical Reviews Database - Guide for Reviewers states that "multiplication indicated by juxtaposition is carried out before
division." Thus, in general, for any variables a, b and c, we would
have a/bc = a/(bc) (assuming, of course, that b and c are nonzero).

Btw, there are threads all over the web arguing this equation.

This is what a professor is saying he was taught back in the 60's.


As I remember them being taught to me, the rules giving the precedence
order for the four arithmetic operations are:

  (1) all multiplication (in any order)
  (2) all division, as they occur from left to right
  (3) all addition and subtraction, as they occur from left to right

  I am actually the only one who got it right at first by pointing out that the terms between parenthesis should be solved first. But yes, I didn't see the two multiplying there. If that makes you feel better, I admit I made a mistake there.
