Show answers and working
1. 14
Subtracting (-8) is the same as adding 8. 6 + 8 = 14
2. 0
Start at 8 on a number line. Move 8 left. You land on 0.
3. 2
Subtracting (-2) is the same as adding 2. 0 + 2 = 2
4. 1
Subtracting (-1) is the same as adding 1. 0 + 1 = 1
5. 100
Multiply the sizes: 10 × 10 = 100. Same signs give positive, different signs give negative. Answer: 100
6. 25
Subtracting (-11) is the same as adding 11. 14 + 11 = 25
7. 2
Start at 8 on a number line. Move 6 left. You land on 2.
8. 29
Start at 11 on a number line. Move 18 right. You land on 29.
9. 17
Start at -10 on a number line. Move 27 right. You land on 17.
10. -1
Subtracting (-3) is the same as adding 3. -4 + 3 = -1
11. -13
Start at 7 on a number line. Move 20 left. You land on -13.
12. -493
Multiply the sizes: 29 × 17 = 493. Same signs give positive, different signs give negative. Answer: -493
Worked examples
9 − (-8) = ?
- Subtracting (-8) is the same as adding 8.
- 9 + 8 = 17
- Answer: 17
6 − 5 = ?
- Subtracting 5 is the same as adding -5.
- 6 + (-5) = 1
- Answer: 1
-7 − 20 = ?
- Subtracting 20 is the same as adding -20.
- -7 + (-20) = -27
- Answer: -27

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
