This is how I learned my order of operations:
Please Excuse My Dear Aunt Sally
which means that you must solve equations in this order:
First, you solve everything that is in a parenthesis. (the please)
Then, you evaluate an exponents. (excuse)
The order doesn't matter, just go from left to right and solve all that is multiplying and diving. (my dear)
And finally add and subtract from the left to the right.
