I think I get the problem- it's the way it's written. I think if it were 48 / 2(12) then the answer is two. However, this one is written with (9+3), and this is what's throwing it off. People are adding the 9 and 3 and getting 2(12) which you would then assume is 2 times 12 and needs to be done first because it's in a parenthesis, but I don't think that is correct. But the (9+3) is like a place holder. I don't fully get it, but if I'm close can someone confirm at least a little? The fact that it's (9+3) and not (12) is somehow the place where everything is getting fucked up. So really it's 48 / 2 X 12, which is 288.
