Show answers and working
1. -1
Subtracting (-6) is the same as adding 6. -7 + 6 = -1
2. -14
Start at -4 on a number line. Move 10 left. You land on -14.
3. -16
Subtracting 8 is the same as adding -8. -8 + (-8) = -16
4. -5
Subtracting (-2) is the same as adding 2. -7 + 2 = -5
5. 1
Start at 3 on a number line. Move 2 left. You land on 1.
6. -17
Subtracting (-3) is the same as adding 3. -20 + 3 = -17
7. 11
Subtracting (-9) is the same as adding 9. 2 + 9 = 11
8. 13
Subtracting (-6) is the same as adding 6. 7 + 6 = 13
9. -49
Subtracting 20 is the same as adding -20. -29 + (-20) = -49
10. -35
Subtracting 9 is the same as adding -9. -26 + (-9) = -35
11. -17
Start at 11 on a number line. Move 28 left. You land on -17.
12. -184
Multiply the sizes: 23 × 8 = 184. Same signs give positive, different signs give negative. Answer: -184
