Show answers and working
1. 10
Subtracting (-6) is the same as adding 6. 4 + 6 = 10
2. 2
Subtracting (-9) is the same as adding 9. -7 + 9 = 2
3. 3
Subtracting 6 is the same as adding -6. 9 + (-6) = 3
4. -2
Subtracting 7 is the same as adding -7. 5 + (-7) = -2
5. -8
Start at -14 on a number line. Move 6 right. You land on -8.
6. -10
Subtracting 18 is the same as adding -18. 8 + (-18) = -10
7. 7
Start at 4 on a number line. Move 3 right. You land on 7.
8. 0
Subtracting (-9) is the same as adding 9. -9 + 9 = 0
9. 18
Subtracting 11 is the same as adding -11. 29 + (-11) = 18
10. -192
Multiply the sizes: 8 × 24 = 192. Same signs give positive, different signs give negative. Answer: -192
11. -6
Start at -23 on a number line. Move 17 right. You land on -6.
12. -18
Start at -4 on a number line. Move 14 left. You land on -18.
Worked examples
5 − (-4) = ?
- Subtracting (-4) is the same as adding 4.
- 5 + 4 = 9
- Answer: 9
-7 + 12 = ?
- Start at -7 on a number line.
- Move 12 right.
- You land on 5.
- Answer: 5
22 + (-15) = ?
- Start at 22 on a number line.
- Move 15 left.
- You land on 7.
- Answer: 7

Common mistakes
What learners typically get wrong, and how to fix it.
Thinks −8 is bigger than −3.
Correction: Further left on the number line means smaller.
Treats − (−4) as −4.
Correction: Two minus signs together become a plus.
Teacher tips
