It is parentheses, exponents, multiplication, division, addition, and subtraction. A good way to remember this is; Please Excuse My Dear Aunt Sally. And always work from left to right.

The usual rules are that first, you must do any operations within parentheses. Then (and also, within the parentheses) you:

* First do all powers

* Then do all multiplications and divisions from left to right

* Then do all additions and subtractions from left to right

There are a few additional rules, but those are the main ones.
