Front

Solve: 3 + 4 × 2

Back

11 (First multiply 4 × 2 = 8, then add 3 + 8 = 11).

Front

Solve: (5 + 3) × 2

Back

16 (First add 5 + 3 = 8, then multiply 8 × 2 = 16).

Front

Solve: 10 - 4 ÷ 2

Back

8 (First divide 4 ÷ 2 = 2, then subtract 10 - 2 = 8).

Front

Solve: 12 + 6 × (2 + 1)

Back

30 (First solve inside parentheses 2 + 1 = 3, then multiply 6 × 3 = 18, finally add 12 + 18 = 30).
