Front

Calculate: 6 ÷ 2 + 3 × 4

Back

15 (First, divide 6 ÷ 2 = 3, then multiply 3 × 4 = 12, and finally add 3 + 12 = 15.)

Front

What is the value of 5 × (2 + 3)?

Back

25 (First, add 2 + 3 = 5, then multiply by 5.)

Front

Calculate: 12 ÷ (2 + 4)

Back

2 (First, add 2 + 4 = 6, then divide 12 ÷ 6 = 2.)

Front

What is the result of 4 + 3 × 2 - 1?

Back

10 (First, multiply 3 × 2 = 6, then add 4 + 6 = 10, and finally subtract 1.)

Front

Calculate: 7 + 2 × (3 + 4)

Back

21 (First, add 3 + 4 = 7, then multiply 2 × 7 = 14, and finally add 7 + 14 = 21.)
