Show answers and working
1. -16
Start at -6 on a number line. Move 10 left. You land on -16.
2. 6
Subtracting (-7) is the same as adding 7. -1 + 7 = 6
3. -6
Subtracting 6 is the same as adding -6. 0 + (-6) = -6
4. 8
Subtracting (-7) is the same as adding 7. 1 + 7 = 8
5. 17
Subtracting (-2) is the same as adding 2. 15 + 2 = 17
6. -3
Start at 5 on a number line. Move 8 left. You land on -3.
7. -288
Multiply the sizes: 18 × 16 = 288. Same signs give positive, different signs give negative. Answer: -288
8. -17
Subtracting 8 is the same as adding -8. -9 + (-8) = -17
9. 5
Start at -20 on a number line. Move 25 right. You land on 5.
10. 29
Start at 11 on a number line. Move 18 right. You land on 29.
11. -46
Multiply the sizes: 23 × 2 = 46. Same signs give positive, different signs give negative. Answer: -46
12. -46
Subtracting 17 is the same as adding -17. -29 + (-17) = -46
Worked examples
-7 − (-7) = ?
- Subtracting (-7) is the same as adding 7.
- -7 + 7 = 0
- Answer: 0
-8 − 16 = ?
- Subtracting 16 is the same as adding -16.
- -8 + (-16) = -24
- Answer: -24
-16 − 21 = ?
- Subtracting 21 is the same as adding -21.
- -16 + (-21) = -37
- Answer: -37
