Show answers and working
1. 8
Start at 6 on a number line. Move 2 right. You land on 8.
2. 9
Subtracting 0 is the same as adding 0. 9 + 0 = 9
3. 4
Start at 4 on a number line. Move 0 right. You land on 4.
4. -4
Subtracting (-5) is the same as adding 5. -9 + 5 = -4
5. -96
Multiply the sizes: 16 × 6 = 96. Same signs give positive, different signs give negative. Answer: -96
6. 14
Start at 11 on a number line. Move 3 right. You land on 14.
7. -30
Multiply the sizes: 10 × 3 = 30. Same signs give positive, different signs give negative. Answer: -30
8. 27
Start at 20 on a number line. Move 7 right. You land on 27.
9. -286
Multiply the sizes: 13 × 22 = 286. Same signs give positive, different signs give negative. Answer: -286
10. -37
Subtracting 20 is the same as adding -20. -17 + (-20) = -37
11. 25
Start at -2 on a number line. Move 27 right. You land on 25.
12. -11
Subtracting 8 is the same as adding -8. -3 + (-8) = -11
Worked examples
8 − 4 = ?
- Subtracting 4 is the same as adding -4.
- 8 + (-4) = 4
- Answer: 4
-11 + 14 = ?
- Start at -11 on a number line.
- Move 14 right.
- You land on 3.
- Answer: 3
30 − 4 = ?
- Subtracting 4 is the same as adding -4.
- 30 + (-4) = 26
- Answer: 26

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
