Except that's not how it was written. If it was meant to be a denominator then he would have written the whole denominator underneath(imo). "/" means to divide.. an "_" would indicate denominator...so if you read it out loud to your self its written as 48 divided by 2 times 12.

Leviathan.Dethard said: Even if you attempt to convert it all to multiplication and division you must first deal with the brackets
48/2(9+3) = 48/2(12)
you still have a bracket to deal with before proceeding to multiplication and division, hence why I feel the multiplication implied by the brackets must be carried out first.
I may be wrong but I still believe the answer is 2 Unless (9+3) is specifically in the denominator, it is still going to be 288.
Even getting rid of (9+3) first, if it's in the numerator, you'd multiply it by 48 not by 2, to get 576/2
Again as written, it's ambiguous.
If it was clearly in the numerator, it could have been written much better and same goes for the denom.

And if you follow that the answer is and can only be 288.
If (9+3) is in the numerator, that is true. The way this question is asked leaves ambiguity as to whether it is in the numerator or denominator. If it's in the denom, then the answer is not 288, even following that.
True but this is how it was written...if the OP wanted to put it as the num/den then he would have done so....unless he failed. You're assuming the way the question is written isn't intentionally left open in the way it is.
As it is written its straight forward... 48 divided by 2 multiplied by 12. Left to right like reading a book(an English book)...this is grade 6 math. When in doubt K.I.S.S it... Keep It Simple Stupid.
Also dude who's to say that the mathematical equation written the exact same would need to follow the rules of LEFT to RIGHT in a different language? i.e. a language that is not read left to right.. that's just 1 small part that makes this so interesting
Umm...math is universal regardless of language "dude". 1+1 is 2 regardless of what tongue I speak. Nice try tho.

Ok, prove it find the rule of operation in languages that do not read left to right. I never said I was correct I simply threw the question out there.

I may be wrong but I still believe the answer is 2
The only problem with this is that the PEMDAS rules say to carry out what's inside the parentheses / brackets not what's outside. But Since it's an implied multiplication even though it's not in the actual laws of PEMDAS I think it would sure makes sense to carry it out first.

The point of my post was you felt the need to come in here and tell us how you don't give a ***about the discussion, you could have easily just not posted.
The add-on part was about a pet peeve many people have about the phrase "I could care less" trying to play it off as a typo or a pretending someone fixing this phrase is the same as a grammar Nazi is just incorrect. The fact is you more than likely physically say "I could care less" even though it's the exact opposite of what you're trying to communicate. It has nothing to do with correcting typical GN typos such as your vs you're.
You're really just sidetracking the nice conversation going on about the equation you don't have any interest in. I would love to get back on topic.

I did add something though. I stated it was a poorly written equation. And, your correction is no different than a your vs. you're thing. So, yeah, grammar nazi fits pretty well.

Yes it can be seen that way..but it would be the wrong way. Taking the whole equation into account from left to right(once brackets are done) its still 48÷2 (step one) then multiplied by 12 (next step)...giving us 288.

48/2(9+3) was written this way prolly cuz he didnt know how to find the ÷ symbol...like me. If he did 48÷2(9+3) we'd have no problem...i hope. Or 48÷2x12. Either way I got a huge headache D:

Replace 2 with x and set it equal to 288.
48/x(9+3)=288
x=?

x=? Answer will still change depending on whether you count (9+3) in the numerator or denom.
Because in one you would multiply by (9+3) and in the other you'd divide by it.

I don't even know, we are all looking at it differently, while at the same time we are using the rules taught to us during our early school years. The way I see it, 2 and (9+3) are grouped together like 2(9+3) except there's no definite bracket around the whole thing so it's too ambiguous. If you saw x(9+3) in the denominator you would have to distribute, and that is where I am coming from. But it's really pointless to argue and start flaming each other over something like this, it's all in the interpretation.

Is anyone using the distributive law? If you use it, you get 2.
Even if it's written with the division sign or shown as a fraction, they both mean the same.
For example, 1/2 is 1 divided by two. In other words, 1 whole divided into two separate halves.
All I want to know is the answer to this problem:
48÷2(9+3)
Let the rage commence.
