1. -10
Subtracting 9 is the same as adding -9. -1 + (-9) = -10
2. 1
Subtracting (-9) is the same as adding 9. -8 + 9 = 1
3. 0
Subtracting 9 is the same as adding -9. 9 + (-9) = 0
4. 18
Subtracting (-10) is the same as adding 10. 8 + 10 = 18
5. 12

Worked examples
9 − (-1) = ?
- Subtracting (-1) is the same as adding 1.
- 9 + 1 = 10
- Answer: 10
10 × 20 = ?
- Multiply the sizes: 10 × 20 = 200.
- Same signs give positive, different signs give negative.
- Answer: 200
- Answer: 200
4 × (-4) = ?
- Multiply the sizes: 4 × 4 = 16.
- Same signs give positive, different signs give negative.
- Answer: -16
- Answer: -16
