Show answers and working
1. -12
Start at -4 on a number line. Move 8 left. You land on -12.
2. -5
Subtracting (-5) is the same as adding 5. -10 + 5 = -5
3. -7
Subtracting 3 is the same as adding -3. -4 + (-3) = -7
4. 16
Start at 7 on a number line. Move 9 right. You land on 16.
5. -14
Subtracting (-5) is the same as adding 5. -19 + 5 = -14
6. 0
Multiply the sizes: 5 × 0 = 0. Same signs give positive, different signs give negative. Answer: 0
7. -39
Subtracting 20 is the same as adding -20. -19 + (-20) = -39
8. 19
Subtracting (-13) is the same as adding 13. 6 + 13 = 19
9. -399
Multiply the sizes: 19 × 21 = 399. Same signs give positive, different signs give negative. Answer: -399
10. -10
Subtracting (-17) is the same as adding 17. -27 + 17 = -10
11. -25
Start at -1 on a number line. Move 24 left. You land on -25.
12. -35
Start at -7 on a number line. Move 28 left. You land on -35.
Worked examples
6 − 0 = ?
- Subtracting 0 is the same as adding 0.
- 6 + 0 = 6
- Answer: 6
5 × 0 = ?
- Multiply the sizes: 5 × 0 = 0.
- Same signs give positive, different signs give negative.
- Answer: 0
- Answer: 0
17 + 19 = ?
- Start at 17 on a number line.
- Move 19 right.
- You land on 36.
- Answer: 36

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
