Show answers and working
1. -11
Start at -9 on a number line. Move 2 left. You land on -11.
2. 10
Subtracting (-1) is the same as adding 1. 9 + 1 = 10
3. -14
Start at -6 on a number line. Move 8 left. You land on -14.
4. 5
Start at 1 on a number line. Move 4 right. You land on 5.
5. -5
Subtracting 4 is the same as adding -4. -1 + (-4) = -5
6. -14
Multiply the sizes: 1 × 14 = 14. Same signs give positive, different signs give negative. Answer: -14
7. 14
Start at 12 on a number line. Move 2 right. You land on 14.
8. 16
Subtracting 0 is the same as adding 0. 16 + 0 = 16
9. 575
Multiply the sizes: 23 × 25 = 575. Same signs give positive, different signs give negative. Answer: 575
10. 12
Start at -18 on a number line. Move 30 right. You land on 12.
11. 336
Multiply the sizes: 24 × 14 = 336. Same signs give positive, different signs give negative. Answer: 336
12. 8
Subtracting (-22) is the same as adding 22. -14 + 22 = 8
Worked examples
-3 − 10 = ?
- Subtracting 10 is the same as adding -10.
- -3 + (-10) = -13
- Answer: -13
-11 − (-3) = ?
- Subtracting (-3) is the same as adding 3.
- -11 + 3 = -8
- Answer: -8
19 + (-13) = ?
- Start at 19 on a number line.
- Move 13 left.
- You land on 6.
- Answer: 6

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
- · Compare winter temperatures from the weather forecast.
Real-life applications
