Show answers and working
1. -1
Subtracting 3 is the same as adding -3. 2 + (-3) = -1
2. -6
Start at -9 on a number line. Move 3 right. You land on -6.
3. -9
Subtracting 1 is the same as adding -1. -8 + (-1) = -9
4. -9
Start at -1 on a number line. Move 8 left. You land on -9.
5. 39
Start at 19 on a number line. Move 20 right. You land on 39.
6. 6
Start at 20 on a number line. Move 14 left. You land on 6.
7. -18
Subtracting 7 is the same as adding -7. -11 + (-7) = -18
8. -32
Multiply the sizes: 4 × 8 = 32. Same signs give positive, different signs give negative. Answer: -32
9. 2
Subtracting (-3) is the same as adding 3. -1 + 3 = 2
10. 273
Multiply the sizes: 13 × 21 = 273. Same signs give positive, different signs give negative. Answer: 273
11. -17
Start at -25 on a number line. Move 8 right. You land on -17.
12. -72
Multiply the sizes: 3 × 24 = 72. Same signs give positive, different signs give negative. Answer: -72
Worked examples
-8 − 6 = ?
- Subtracting 6 is the same as adding -6.
- -8 + (-6) = -14
- Answer: -14
1 × 1 = ?
- Multiply the sizes: 1 × 1 = 1.
- Same signs give positive, different signs give negative.
- Answer: 1
- Answer: 1
9 × 25 = ?
- Multiply the sizes: 9 × 25 = 225.
- Same signs give positive, different signs give negative.
- Answer: 225
