If it were written:
48÷(2(9+3))
48÷(2(12))
48÷(2*12)
48÷24
=2
But it's not written like that which is what people don't seem to get.
what you don't seem to get is because of convention, different calculators will get different answers. calculators are supposed to be masters of OOO.
Then your problem is that you're relying on your calculator to much. I'm sorry to tell you, but it's true. If your calculator came up with the wrong answer, then you used it wrong or you read the question wrong.
I really can't be bothered to go find the pic, but somebody put the equation as written into four different calculators. Two said 288, the other two said 2. I can tell you that entering 48/2(9+3) gives 288 via Google's calculator, but 2 on my Casio. If I knew where my TI-89 was right off hand I'd go find it and see what it said for shiggles.
There is no error. Neither answer is wrong given the ambiguous syntax.
