What is the Order of Operations?

Back

The Order of Operations is a set of rules that tells you the correct sequence to evaluate a mathematical expression. The order is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Often remembered by the acronym PEMDAS.

Simplify the expression: (9 x 2) - 2 x 4

Back

First, calculate (9 x 2) = 18, then calculate (2 x 4) = 8. Finally, 18 - 8 = 10.
