Front

Calculate: 3 + 4 x 6 - 4

Back

First, multiply: 4 x 6 = 24, then add and subtract: 3 + 24 - 4 = 23.

Front

Calculate: (9 + 23) ÷ (5 - 3)

Back

First, solve inside the parentheses: 9 + 23 = 32 and 5 - 3 = 2. Then divide: 32 ÷ 2 = 16.

Front

Calculate: 18 + 2 x 4

Back

First, multiply: 2 x 4 = 8, then add: 18 + 8 = 26.

Front

Calculate: 18 - 4 x 2

Back

First, multiply: 4 x 2 = 8, then subtract: 18 - 8 = 10.
