This has been done to death...
It depends on which rule set you going with...

I saw this in a 9Gag thread now, and the comments were crazy. Since I know all of you are so clever, what is the answer to this question?
48 ÷ 2(9 + 3) = ?

For example google gives...
(48 / 2) * (9 + 3) = 288
More about calculator.
(48 / 2) * (9 + 3) = 288
More about calculator.
but one can argue thoughWhere did the second set of brackets come from ? You have changed the question.

Try put in the original formula...
Taking the rule of BODMAS: (Brackets of Division, Multiplication, Addition and Subtraction)
There are two ways you can go about this:
1) Take 2 * (9+3)
2) or take that part as (2*(9+3), which is how a scientific calculator (which applies bodmas) sees it. The 2(...) is seen as (2(...)).
Therefore
48 ÷ 2(9 + 3)
(Using #2)
= 48 ÷ [(2*(9+3)) = 24]
= 48 ÷ 24
=2
Taking #1 you end up with 288.

And this is why using the divide sign is silly.
Do anything half serious and it will always be
x
y
Completely eliminates this whole matter of people forgetting that when left with only division and multiplication you read the equation from left to right

A calculator is only as good as whoever implemented the logic.

Fine, I'll just leave this here for you guys to disprove. It's exactly the same thing as the original statement. Adding brackets because you can't visualise the equation is your own fault.
I agree with Mike on something. :wtf:
Could it not be the fact that calculators are made in the East (Japan, Korea) and they work from right to left

Ah damn, I only saw the toon now, sorry.
There are different rulesets
certainly there can be only one answer as math is supposed to be a universal language???
