Whoever says this is grade 10 math needs to go back to grade 5 or 6 when we actually learned about this lol

It's a poorly written equation designed to spark a heated debate (which it has). An equation written in bad form begets ambiguity which begets multiple interpretations. Ask any knowledgeable math professor and he will tell you the equation is ambiguous because of the way it is written.
The only idiots are the ones who got something other than 2 or 288.

calculator: 48 ÷ 2(9+3) = 2
excel: 48 / 2(9+3) = 288
excel: 48 / (2(9+3)) = 2
but seeing how its written like 48 ÷ 2(9+3), i say 2

who ever is getting a 2 is a retard.
BEDMAS is not wrong, learn how to apply it.
One more thing, I would trust excel more than the calculator most of the time.

Get off your high horse. | Sorry, how is the equation ambiguous? I really don't see how this can be. Is BEDMAS invalidated now that people are plugging numbers into the calculator? What rule are people using to come to the answer 2?

no, you said accounting FTW
so i assumed you mean you are either taking accounting now, or are an accountant.
cause when i said engineering ftw, because im currently in school for mechanical engineering...

48 ÷ 2(9+3)
48 ÷ 2(12)
48 ÷ 24
2
there's a bracket around the 12, so you would get rid of that first before you divide.
There is only one answer for this the way the OP posted. The only reason people get different answers is because the way their calculators interpret the answer.(Any scientific calculator will get 2)
LOL at how sure presto is about 288 being the answer

48 ÷ 2(12) is the same as 48 ÷ 2 x 12.

There's no longer any equation within the brackets to deal with. The number 2, next to the bracket just means you multiply 2 by whatever is in there. You just have to look at it like this: 48 / 2 * 12, then apply BEDMAS. Quote:

The problem here is the operator, and how the data was entered. So, tell me, other than BEDMAS, what is the way to solve this. Again, the equation holds no ambiguity. It can and is solvable with BEDMAS.
The only way you can get this equation: is if the original equation ( 48÷2(9+3)) is written as 48÷(2(9+3))

48 ÷ 2(12) is the same as 48 ÷ 2 x 12. | your saying that the brackets around the 12 are insignificant and just changing the "( )" to a "x" thus changing the meaning of the equation
48 ÷ 2(12)= 2
(put those into any scientific calculator and you can confirm)
48 ÷ 2 x 12=288
if you cant see why that is true then good luck to you

Back to grade 5 for you:
Order of Operations
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. 48 ÷ 2(12) =
24(12) = 288

Like someone said before, it's a bad layout of the equation and I haven't seen an actual division sign (can't even find one on my keyboard) in years. If the question had any importance and context of the numbers was known, or how the equation was derived, one could easily figure out how to properly lay it out.
As it is...Presto is correct and the answer is 288, however, the logical way of interpreting the badly laid out equation would get 2

What rule are people using to come to the answer 2? | it's ambiguous because when someone asks you to interpret 1/2x you don't know whether they mean (1/2)x or 1/(2x). 9 times out of 10 they mean 1/(2x) because the 2 and the x are implied to be together (kinda like the 2(9+3) here) and they are either lazy (bastards!) or don't know how to use brackets to avoid confusion.
I'm not saying interpreting it as 1/(2x) is 'correct'. The first thing I would do is get them to clarify if they mean
(1/2)x or
1/(2x)
that's the proper way to type out the equation to avoid confusion.
