Front

What is the order of operations in mathematics?

Back

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

Evaluate: 3 + 5 x 2

Back

13 (First, multiply 5 x 2 = 10, then add 3.)

Front

Evaluate: (4 + 2) x 3

Back

18 (First, add 4 + 2 = 6, then multiply by 3.)

What is the first step in evaluating 8 - 7 + 12 ÷ (3 + 1)?

Back

Add 3 and 1 (First, solve the expression inside the parentheses.)

Front

Evaluate: 7 + 3 x 4 - 2

Back

17 (First, multiply 3 x 4 = 12, then add 7 and subtract 2.)

Front

What is the value of 2²?

Back

4 (2 squared means 2 multiplied by itself.)

Front

Evaluate: 8 x 3² ÷ 3

Back

24 (First, calculate 3² = 9, then multiply 8 x 9 = 72, and finally divide by 3.)

Front

What is the value of 24 ÷ 6 x 2²?

Back

16 (First, calculate 2² = 4, then divide 24 by 6 = 4, and finally multiply by 4.)

Front

Evaluate: 5 x 2 - (11 - 7)

Back

6 (First, solve the parentheses: 11 - 7 = 4, then multiply 5 x 2 = 10, and finally subtract 4.)
