For example,
- (–13) × (–15) = 195
- (–24) ÷ 9 = `(-24)/9 = (-8)/3`

उत्तर
1. The four such multiplications are
- (−27) × (−15) = 405
- (+41) × (+13) = 533
- (−28) × (−8) = 224
- (−37) × (+12) = −444
2. The four such division are
- (−24) ÷ (+9) = `-24/9 = -8/3`
- (−13) ÷ (−15) = `13/15`
- (+41) ÷ (−27) = `-41/27`
- (+12) ÷ (−18) = `-12/18 = -2/3`
