Show answers and working
1. -2
Subtracting 0 is the same as adding 0. -2 + 0 = -2
2. 0
Subtracting (-7) is the same as adding 7. -7 + 7 = 0
3. 11
Subtracting (-1) is the same as adding 1. 10 + 1 = 11
4. -2
Subtracting (-1) is the same as adding 1. -3 + 1 = -2
5. 19
Start at 10 on a number line. Move 9 right. You land on 19.
6. -12
Start at -3 on a number line. Move 9 left. You land on -12.
7. 252
Multiply the sizes: 18 × 14 = 252. Same signs give positive, different signs give negative. Answer: 252
8. -11
Start at 2 on a number line. Move 13 left. You land on -11.
9. 667
Multiply the sizes: 23 × 29 = 667. Same signs give positive, different signs give negative. Answer: 667
10. -30
Start at -1 on a number line. Move 29 left. You land on -30.
11. -312
Multiply the sizes: 12 × 26 = 312. Same signs give positive, different signs give negative. Answer: -312
12. -546
Multiply the sizes: 26 × 21 = 546. Same signs give positive, different signs give negative. Answer: -546
Worked examples
7 + (-8) = ?
- Start at 7 on a number line.
