Order of Operations with Exponents

Front

What is the Order of Operations?

Back

The Order of Operations is 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 remembered by the acronym PEMDAS.

What does 'exponent' mean in mathematics?

Back

An exponent is a number that shows how many times a base is multiplied by itself. For example, in 2^3 (2 raised to the power of 3), 2 is the base and 3 is the exponent, meaning 2 x 2 x 2.
