Order of operations is a set of rules that tells you which calculations to do first when solving multi-step math equations. It's important to follow the rules, so that you get the correct answer. The order of operations is: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction (PEMDAS)

Order of operations is the order in which operations are performed when evaluating a mathematical expression. It is important to follow the order of operations when solving a problem in order to get the correct answer. The order of operations is usually expressed as PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). When solving an equation, use the order of operations to simplify the equation and work through the problem step by step to get the correct answer.
