Now, let's solve each problem:

---

1. -106 + 40

- One is negative, one is positive.
- Compare absolute values: |–106| = 106, |40| = 40 → 106 > 40
- So, the result will be negative
- Subtract: 106 – 40 = 66
- Answer: -66

---

2. 13 + (-30)

- Same as 13 – 30
- 30 > 13, so result is negative
- 30 – 13 = 17
- Answer: -17

---

3. 57 + (-15)

- 57 is positive, -15 is negative
- 57 > 15 → positive result
- 57 – 15 = 42
- Answer: 42

---

4. 26 + 66

- Both positive → add them
- 26 + 66 = 92
- Answer: 92

---

5. 82 + 139

- Both positive → add
- 82 + 139 = 221
- Answer: 221

---

6. 17 + 54

- Both positive → add
- 17 + 54 = 71
- Answer: 71

---

7. -9 + (-1)

- Both negative → add their absolute values and keep negative sign
- 9 + 1 = 10 → -10
- Answer: -10

---

8. -29 + (-73)

- Both negative → add absolute values
- 29 + 73 = 102 → -102
- Answer: -102

---

9. 124 + (-18)

- 124 is positive, -18 is negative
- 124 > 18 → positive result
- 124 – 18 = 106
- Answer: 106

---

10. 46 + (-2)

- 46 > 2 → positive result
- 46 – 2 = 44
- Answer: 44

---

11. 38 + (-33)

- 38 > 33 → positive result
- 38 – 33 = 5
- Answer: 5

---

12. 73 + 124

- Both positive → add
- 73 + 124 = 197
- Answer: 197
