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 acronym PEMDAS is often used to remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

Evaluate the expression: 5 + 2 x 3.

Back

The answer is 11, because you perform multiplication first: 2 x 3 = 6, then add 5.

Front

Evaluate the expression: (4 + 6) x 2.

Back

The answer is 20, because you first evaluate the parentheses: 4 + 6 = 10, then multiply by 2.

What is the result of 8 + 2^3?

Back

The result is 16, because you evaluate the exponent first: 2^3 = 8, then add 8.
