Order of operations are guidelines that inform which operation to perform first. Consider the following example.

Which operation should be performed first?

Order of operations ranks the operations:

- Simplify what is inside brackets
- Evaluate Exponents
- Multiplication and Division (perform from left to right if they are consecutive operations)
- Addition and Subtraction (perform from left to right if they are consecutive operations)
