Show answers and working
1. 1
Subtracting (-1) is the same as adding 1. 0 + 1 = 1
2. 0
Start at 1 on a number line. Move 1 left. You land on 0.
3. -6
Start at -8 on a number line. Move 2 right. You land on -6.
4. -9
Subtracting 0 is the same as adding 0. -9 + 0 = -9
5. 210
Multiply the sizes: 14 × 15 = 210. Same signs give positive, different signs give negative. Answer: 210
6. 17
Start at 2 on a number line. Move 15 right. You land on 17.
7. 16
Start at -1 on a number line. Move 17 right. You land on 16.
8. 5
Subtracting (-17) is the same as adding 17. -12 + 17 = 5
9. 33
Start at 23 on a number line. Move 10 right. You land on 33.
10. 216
Multiply the sizes: 8 × 27 = 216. Same signs give positive, different signs give negative. Answer: 216
11. -145
Multiply the sizes: 29 × 5 = 145. Same signs give positive, different signs give negative. Answer: -145
12. -400
Multiply the sizes: 25 × 16 = 400. Same signs give positive, different signs give negative. Answer: -400
Worked examples
5 − 5 = ?
- Subtracting 5 is the same as adding -5.
- 5 + (-5) = 0
- Answer: 0
12 − (-11) = ?
- Subtracting (-11) is the same as adding 11.
- 12 + 11 = 23
- Answer: 23
-26 + (-14) = ?
- Start at -26 on a number line.
- Move 14 left.
- You land on -40.
- Answer: -40
