Working left to right (Which is how I was taught), I find the same results with PEDMAS or GEMA.



With PEDMAS, after parenthesis, I'm left with 6/2x3. Then 3x3, then 9.

With GEMA, it becomes 3(3)...and then, well, 9.

I don't know if my methods are the most correct, but they keep my answer consistent.
