Someone please feel free to correct me if I'm remembering this wrong--after all, it was back in 1982 that I took College Algebra.

There shouldn't be any ambiguity about this equation because you're supposed to solve the contents of parentheses first, hence we do the (1+2) to get 3. Then, since the remainder of the problem involves division and multiplication, we simply go from left to right to solve it.

We have:

6 / 2 * (1 + 2) or

(6 / 2) * (1+2) or

(6 / 2) * (3) or

(3) * (3) for an answer of 9.

Right...?
