Show answers and working
1. 9
Start at 4 on a number line. Move 5 right. You land on 9.
2. -11
Subtracting 4 is the same as adding -4. -7 + (-4) = -11
3. -6
Subtracting 6 is the same as adding -6. 0 + (-6) = -6
4. -7
Start at -3 on a number line. Move 4 left. You land on -7.
5. -24
Multiply the sizes: 3 × 8 = 24. Same signs give positive, different signs give negative. Answer: -24
6. 7
Start at 1 on a number line. Move 6 right. You land on 7.
7. 5
Subtracting 11 is the same as adding -11. 16 + (-11) = 5
8. 3
Subtracting 6 is the same as adding -6. 9 + (-6) = 3
9. 34
Subtracting (-29) is the same as adding 29. 5 + 29 = 34
10. -90
Multiply the sizes: 10 × 9 = 90. Same signs give positive, different signs give negative. Answer: -90
11. 17
Subtracting (-3) is the same as adding 3. 14 + 3 = 17
12. 22
Subtracting (-4) is the same as adding 4. 18 + 4 = 22
Worked examples
10 + 10 = ?
- Start at 10 on a number line.
- Move 10 right.
- You land on 20.
- Answer: 20
18 − 11 = ?
- Subtracting 11 is the same as adding -11.
- 18 + (-11) = 7
- Answer: 7
-29 − (-26) = ?
- Subtracting (-26) is the same as adding 26.
- -29 + 26 = -3
- Answer: -3
