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.
Parentheses (Please) Exponents (Excuse) Multiplication (My) Division (Dear) Addition (Aunt) Subtraction (Sally)
If you put in parentheses, you can change the order of operations in many cases, as parentheses come before everything in the order of operations.
It means that the calculator can follow the order of operations and do the order of operations for you but, you need to know how to do them on your own too.
We have to use the order of operations so everyone solves a problem the same.
