order of operations

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

Front

Calculate: 5 + 2 × 3

Back

11 (First, multiply 2 × 3 = 6, then add 5 + 6 = 11).

Front

Calculate: (8 - 3) × 2 + 4

Back

14 (First, calculate inside the parentheses: 8 - 3 = 5, then multiply: 5 × 2 = 10, and finally add: 10 + 4 = 14).

Front

What is the result of 10 ÷ 2 + 3 × 4?

Back

16 (First, divide: 10 ÷ 2 = 5, then multiply: 3 × 4 = 12, and finally add: 5 + 12 = 17).

Front

What is the value of 2 + 3 × (4 - 1)?

Back

11 (First, calculate inside the parentheses: 4 - 1 = 3, then multiply: 3 × 3 = 9, and finally add: 2 + 9 = 11).

Front

Solve: 6 + 2 × 5 - 3

Back

15 (First, multiply: 2 × 5 = 10, then add: 6 + 10 = 16, and finally subtract: 16 - 3 = 13).

Front

What is the value of (2 + 3)²?

Back

25 (First, calculate inside the parentheses: 2 + 3 = 5, then square: 5² = 25).

Front

Calculate: 4 × (3 + 2) - 6 ÷ 2

Back

18 (First, calculate inside the parentheses: 3 + 2 = 5, then multiply: 4 × 5 = 20, and divide: 6 ÷ 2 = 3, finally subtract: 20 - 3 = 17).

Front

What is the result of 3 + 4² - 2 × 5?

Back

13 (First, calculate the exponent: 4² = 16, then multiply: 2 × 5 = 10, and finally add and subtract: 3 + 16 - 10 = 9).
