Show answers and working
1. -1
Subtracting (-2) is the same as adding 2. -3 + 2 = -1
2. 10
Subtracting (-10) is the same as adding 10. 0 + 10 = 10
3. -12
Subtracting 6 is the same as adding -6. -6 + (-6) = -12
4. -4
Subtracting (-6) is the same as adding 6. -10 + 6 = -4
5. -40
Multiply the sizes: 4 × 10 = 40. Same signs give positive, different signs give negative. Answer: -40
6. 2
Subtracting 7 is the same as adding -7. 9 + (-7) = 2
7. 1
Subtracting (-6) is the same as adding 6. -5 + 6 = 1
8. -17
Subtracting (-1) is the same as adding 1. -18 + 1 = -17
9. 88
Multiply the sizes: 22 × 4 = 88. Same signs give positive, different signs give negative. Answer: 88
10. -37
Start at -11 on a number line. Move 26 left. You land on -37.
11. 6
Subtracting (-28) is the same as adding 28. -22 + 28 = 6
12. -2
Subtracting (-4) is the same as adding 4. -6 + 4 = -2
Worked examples
-1 + (-10) = ?
- Start at -1 on a number line.
- Move 10 left.
- You land on -11.
- Answer: -11
8 + 16 = ?
- Start at 8 on a number line.
- Move 16 right.
- You land on 24.
- Answer: 24
8 − (-7) = ?
- Subtracting (-7) is the same as adding 7.
- 8 + 7 = 15
- Answer: 15
