Back

The order of operations is a set of rules that determines the sequence in which calculations are performed in a mathematical expression. The common acronym to remember this is PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Front

What is the result of (4 + 6) ÷ 2?

Back

5 (because you perform the operation inside the parentheses first).
