Show answers and working
1. 5
Subtracting (-10) is the same as adding 10. -5 + 10 = 5
2. -13
Start at -4 on a number line. Move 9 left. You land on -13.
3. -4
Subtracting 3 is the same as adding -3. -1 + (-3) = -4
4. -7
Start at -1 on a number line. Move 6 left. You land on -7.
5. 33
Start at 13 on a number line. Move 20 right. You land on 33.
6. 180
Multiply the sizes: 10 × 18 = 180. Same signs give positive, different signs give negative. Answer: 180
7. 23
Subtracting (-19) is the same as adding 19. 4 + 19 = 23
8. -29
Subtracting 10 is the same as adding -10. -19 + (-10) = -29
9. -30
Multiply the sizes: 1 × 30 = 30. Same signs give positive, different signs give negative. Answer: -30
10. -19
Start at 2 on a number line. Move 21 left. You land on -19.
11. -136
Multiply the sizes: 8 × 17 = 136. Same signs give positive, different signs give negative. Answer: -136
12. -37
Start at -13 on a number line. Move 24 left. You land on -37.
