Already been done.No it hasn't, replace with symbol and see what it does...The master has spoken.
(hint it's not always that)
Tried it myself and got the same answer.

You are simply incorrect on this one. The implied () are there just as surely as the implied * is there. The extra set of brackets is no more needed to convey the correct meaning than the absent * symbol.Except, the original equation doesn't have the extra set of (). If it had, then the answer is 2. You can't just go around adding shits in that aren't there and say "implied". It's either YES, or NO. ON or OFF. This is not a religion. It's not up for debate. It's not up to your "interpretation". Do you see an extra set of brackets in the original equation? NO!
I see, now you're making up your own rules. Good to know.You are simply incorrect on this one. The implied () are there just as surely as the implied * is there. The extra set of brackets is no more needed to convey the correct meaning than the absent * symbol.
It's okay to admit you're wrong you know. We won't, at least I won't, think less of you.I see, now you're making up your own rules. Good to know.

Who is this "we", the rest of the "the answer is 2" crowd? Take heed of your own advice.It's okay to admit you're wrong you know. We won't, at least I won't, think less of you.

So what is your answer to the sources posted so far, some from math resources, and those who have math degrees, who say that in the world of mathematics (not comp sci) it can be somewhat ambiguous.

Oh really? Why pretend, we both know perfectly well what this is about. You want me to have an abortion.Who is this "we", the rest of the "the answer is 2" crowd? Take heed of your own advice.

It can't be ambiguous.
By ambiguous here I'm not saying there isn't a right answer. I think 288 IS the right answer. But let's say you took this question to 100 math profs and it came back 60/40 in favor of 288. I'd still say then that it's at least somewhat ambiguous as written.
It seems to me quite natural to handle the 2(9+3) as one unit before doing the division. This yields 2. I can certainly see where 288 comes from and why it probably is the right answer here. If you do 9+3 = 12. Then sub in the 12 and get 48/2*12 then you get 288. However again my first instinct is to handle the 2(9+3) as one unit first. Given the number of people who answer both ways and everything I've read so far, wiki and nukeneds link, I'd be willing to say that it is at least SOMEWHAT ambiguous.
there is absolutely NOTHING ambiguous. Your "natural instinct" in math is simply incorrect. You keep insisting that you THINK 288 is the right answer... it IS the right answer. There is no other way to solve the equation.
If you had to solve this: 48/2(9+3)/2(9+3)/2(9+3) how would you do it? using your natural instinct, you could end up with multiple solutions, albeit all wrong.
I wouldn't put any faith in anything that WolframAlpha site says on either side of the debate.
Plug in 48/2(9+3) and it returns an answer of 288, meaning that the program reads it as (48/2)*(9+3).
Plug in 48/a(9+3) and it returns an answer of 48/(a(9+3)), or 48/(12a) or 4/a. Since we know a=2 the returned answer is 2.
The program itself uses different rules with the exact same equations depending on whether a term is represented as a known or unknown. That defies mathematical principals and proves the program is useless for proving anything.

?I don't claim to be a math expert, so I'm curious, in your example, why does 48/a(9+3) become 48/(a(9+3)) and not (48/a)(9+3)? What is the deciding factor that caused you to choose to place parenthesis around the multiplication part of the problem, as opposed to the division part?
?
I fail to see where he said that he made that choice.

To a learning eye that much more clearly shows the proper order of operations. As we get older we look for shortcuts; one of which is going back to a one-line style. In that case anything after the "/" is implied to be in the denominator, otherwise we'd use the notation of (48/2)(9+3). Our brains should see the old-style division symbol and not make that association, that everything after it is part of the denominator, but it is not a common keyboard symbol so our brains subconsciously replace it with "/" and boom, the shorthand implied denominator kicks in again.
