Order of Operations

Front

What is the Order of Operations?

Back

A set of rules that determines the sequence in which calculations are performed in a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often abbreviated as PEMDAS.

What is the first step in solving an expression using the Order of Operations?

Back

Always start with calculations inside Parentheses.

What is the role of Exponents in the Order of Operations?

Back

Exponents are calculated after Parentheses and before Multiplication and Division.
