We first look for any grouping symbols, like parentheses or brackets. If there are any present, you start from the innermost grouping symbols. We clear all exponents and roots, then we multiply and divide from left to right. Then we add and subtract from left to right. IF there aren't any grouping symbols, you still follow that same order.

Most often, students use the memonic Please Excuse My Dear Aunt Sally. This saying (PEMDAS) is used to remember the correct order of operations. It stands for Parentheses, Exponential, (Multiplication, Division) and (Addition and Subtraction). Each equation is scanned four times, doing the math. Multiplication, Division, Addition, and Subtraction.

"Please Excuse My Dear Aunt Sally. " Go through the problem and solve everything in Parentheses first (meaning inside every parenthesis pair you should just have a single number. Then do all exponents, then Multiplication/Division, then Addition/Subtraction. If you have parentheses in parentheses, do the innermost set and work outward. In parentheses, solve using the order like its own problem.

First you are going to want to do anything in parenthesis. Next you want to do all multiplication and division going from left to right followed by adding/subtracting.
