Please Excuse My Dear Aunt Sally. Parentheses, Exponents (left to right, meaning P or E whichever is first), Multiply, Divide (again, left to right), Add, Subtract. :)

Exponents first, PEMDAS Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

At my school it was BIDMAS which meant Brackets, Indices, Multplication, Dvision, Addition and Subtraction. But as indices indicate exponentiation we come to the same conclusion.
So 2x3^2 = 18 not 36.
