Show answers and working
1. 11
Subtracting (-10) is the same as adding 10. 1 + 10 = 11
2. 1
Start at 6 on a number line. Move 5 left. You land on 1.
3. 7
Subtracting (-7) is the same as adding 7. 0 + 7 = 7
4. -9
Start at 1 on a number line. Move 10 left. You land on -9.
5. 8
Subtracting 5 is the same as adding -5. 13 + (-5) = 8
6. 234
Multiply the sizes: 13 × 18 = 234. Same signs give positive, different signs give negative. Answer: 234
7. -3
Subtracting (-3) is the same as adding 3. -6 + 3 = -3
8. 5
Start at 19 on a number line. Move 14 left. You land on 5.
9. -21
Subtracting 21 is the same as adding -21. 0 + (-21) = -21
10. 19
Subtracting (-19) is the same as adding 19. 0 + 19 = 19
11. -4
Subtracting 18 is the same as adding -18. 14 + (-18) = -4
12. -31
Start at -17 on a number line. Move 14 left. You land on -31.
