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 helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

Calculate: 5 + 3 × 2

Back

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

Front

Calculate: (4 + 2) × 3

Back

First, solve the parentheses: 4 + 2 = 6, then multiply: 6 × 3 = 18.

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.

Calculate: 10 - (2 + 3) × 2

Back

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

Front

What is the value of the expression 6 + 2 × (3 - 1)?

Back

First, solve the parentheses: 3 - 1 = 2, then multiply: 2 × 2 = 4, finally add: 6 + 4 = 10.

Front

Calculate: 12 ÷ 4 + 5 × 2

Back

According to the Order of Operations, first divide and multiply: 12 ÷ 4 = 3 and 5 × 2 = 10, then add: 3 + 10 = 13.

What is the value of the expression 7 + 8 - 2?

Back

The value is 13.
