Order of Operations

The order of operations is as follows:

1. Evaluate expressions in parentheses

2. Evaluate exponential expressions

3. Evaluate multiplication and division from left to right

4. Evaluate addition and subtraction from left to right

Simplified, this can be remembered as Parentheses, Exponents, Multiply, Divide, Add, Subtract. The acronym PEMDAS or the phrase "Please Excuse My Dear Aunt Sally" may help.
