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

PEMDAS stands for: P - Parentheses, E - Exponents, MD - Multiplication and Division (from left to right), AS - Addition and Subtraction (from left to right).

Front

Calculate: 5 + 2 × 3

Back

According to the Order of Operations, you should multiply first: 2 × 3 = 6, then add: 5 + 6 = 11.

Front

Calculate: (4 + 3) × 2

Back

First, solve the parentheses: 4 + 3 = 7, then multiply: 7 × 2 = 14.

Front

What is the value of the expression: 8 - 3 + 2?

Back

According to the Order of Operations, perform addition and subtraction from left to right: 8 - 3 = 5, then 5 + 2 = 7.

Front

Calculate: 6 ÷ 2 + 1

Back

First, divide: 6 ÷ 2 = 3, then add: 3 + 1 = 4.

Front

What is the value of the expression: 10 - (2 + 3) × 2?

Back

First, solve the parentheses: 2 + 3 = 5, then multiply: 5 × 2 = 10, finally subtract: 10 - 10 = 0.

Front

Calculate: 3 + 6 ÷ 2 - 1

Back

First, divide: 6 ÷ 2 = 3, then add and subtract from left to right: 3 + 3 - 1 = 5.

Front

What is the value of the expression: 5 × (2 + 3) - 4?

Back

First, solve the parentheses: 2 + 3 = 5, then multiply: 5 × 5 = 25, finally subtract: 25 - 4 = 21.
