    After thought, you might actually be right. For example: a/bc Is it \frac{ac}{b} or is it \frac{a}{bc}? EDIT: Perhaps the ambiguity of the question is getting to me, and I was correct initially: a/bc = \frac{ac}{b}

    If you follow the order of operations, why are you multiplying 2 by twelve before dividing 48 by two? Multiplication doesn't take precedence over division, they're performed from left to right: \frac{48}{2}(9+3)
