Front

Calculate: 3 + 5 × 2

Back

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

Front

Calculate: (8 - 3) × 4

Back

20 (First, subtract 8 - 3 = 5, then multiply 5 × 4.)

Front

Are these two expressions equal? (2 + 3) × 2 and 2 × 2 + 2

Back

No, they are not equal (First equals 10, second equals 6).

Front

Calculate: 10 - 2^3 + 5

Back

13 (First, calculate 2^3 = 8, then 10 - 8 + 5 = 7.)

Front

What is the result of 6 ÷ 2(1 + 2)?

Back

9 (First, calculate inside the parentheses: 1 + 2 = 3, then 6 ÷ 2 × 3 = 9.)

Front

Calculate: 12 - 4 + 2 × 3

Back

14 (First, multiply 2 × 3 = 6, then 12 - 4 + 6 = 14.)

Front

What is the value of 5 × (3 + 2) - 4?

Back

21 (First, calculate inside the parentheses: 3 + 2 = 5, then 5 × 5 - 4 = 21.)

Front

Calculate: 7 + 2 × (3 + 4)

Back

21 (First, calculate inside the parentheses: 3 + 4 = 7, then 2 × 7 + 7 = 21.)
