Question 4:

The fish in the pond below, carry some numbers. Choose any 4 pairs and carry out four multiplications with those numbers. Now, choose four other pairs and carry out divisions with these numbers. 
For example,
1. (–13) × (–15) = 195
2. -24÷9=-249--83

Answer:

The four such multiplications are
(−13) × 9 = 117
(−15) × 12 = −180
(−8) × (−18) = 144
13 × 41 = 533
The four such division are
(−18) ÷ 9 = −2
(−24) ÷ 12 = −2
(−13) ÷ 13 = −1
(−27) ÷ 9 = −3
