Show answers and working
1. -5
Subtracting 5 is the same as adding -5. 0 + (-5) = -5
2. 8
Start at -1 on a number line. Move 9 right. You land on 8.
3. 5
Start at 9 on a number line. Move 4 left. You land on 5.
4. 4
Start at -2 on a number line. Move 6 right. You land on 4.
5. 120
Multiply the sizes: 6 × 20 = 120. Same signs give positive, different signs give negative. Answer: 120
6. 22
Start at 3 on a number line. Move 19 right. You land on 22.
7. -7
Start at -2 on a number line. Move 5 left. You land on -7.
8. 13
Start at 4 on a number line. Move 9 right. You land on 13.
9. 459
Multiply the sizes: 17 × 27 = 459. Same signs give positive, different signs give negative. Answer: 459
10. 28
Multiply the sizes: 4 × 7 = 28. Same signs give positive, different signs give negative. Answer: 28
11. -56
Subtracting 26 is the same as adding -26. -30 + (-26) = -56
12. -140
Multiply the sizes: 7 × 20 = 140. Same signs give positive, different signs give negative. Answer: -140
Worked examples
-4 + 1 = ?
- Start at -4 on a number line.
- Move 1 right.
- You land on -3.
- Answer: -3
19 + 10 = ?
- Start at 19 on a number line.
- Move 10 right.
- You land on 29.
- Answer: 29
-13 − (-2) = ?
- Subtracting (-2) is the same as adding 2.
- -13 + 2 = -11
- Answer: -11

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
- · Use a vertical number line like a thermometer.
Parent tips
