Problem: Adding Integers

The task is to solve the addition of integers for each given pair. Here are the steps and solutions for each problem:

---

#### 1. $(-20) + (-2)$
- When adding two negative numbers, add their absolute values and keep the negative sign.
- Absolute values: $20 + 2 = 22$
- Result: $-22$

Answer: $-22$

---

#### 2. $(-29) + 15$
- When adding a negative number and a positive number, subtract the smaller absolute value from the larger one and keep the sign of the number with the larger absolute value.
- Absolute values: $29 - 15 = 14$
- Since $-29$ has the larger absolute value, the result is negative.
- Result: $-14$

Answer: $-14$

#### 3. $18 + 9$
- Add the two positive numbers directly.
- Result: $27$

Answer: $27$

---

#### 4. $12 + (-6)$
- Subtract the absolute value of the negative number from the positive number.
- Absolute values: $12 - 6 = 6$
- Since $12$ is positive and larger, the result is positive.
- Result: $6$

Answer: $6$

#### 5. $(-11) + 4$
- Subtract the absolute value of the positive number from the absolute value of the negative number.
- Absolute values: $11 - 4 = 7$
- Since $-11$ has the larger absolute value, the result is negative.
- Result: $-7$

Answer: $-7$

#### 7. $8 + 16$
- Add the two positive numbers directly.
- Result: $24$

Answer: $24$

---

#### 8. $24 + (-1)$
- Subtract the absolute value of the negative number from the positive number.
- Absolute values: $24 - 1 = 23$
- Since $24$ is positive and larger, the result is positive.
- Result: $23$

Answer: $23$

#### 9. $(-15) + (-1)$
- When adding two negative numbers, add their absolute values and keep the negative sign.
- Absolute values: $15 + 1 = 16$
- Result: $-16$

Answer: $-16$

---

#### 10. $(-2) + 2$
- When adding a negative number and its positive counterpart (opposite), the result is zero.
- Result: $0$

Answer: $0$

---

#### 11. $(-14) + 6$
- Subtract the absolute value of the positive number from the absolute value of the negative number.
- Absolute values: $14 - 6 = 8$
- Since $-14$ has the larger absolute value, the result is negative.
- Result: $-8$

Answer: $-8$

---

#### 12. $19 + (-9)$
- Subtract the absolute value of the negative number from the positive number.
- Absolute values: $19 - 9 = 10$
- Since $19$ is positive and larger, the result is positive.
- Result: $10$

Answer: $10$

---

#### 13. $28 + 0$
- Adding zero to any number does not change the number.
- Result: $28$

Answer: $28$

---

#### 14. $(-1) + (-13)$
- When adding two negative numbers, add their absolute values and keep the negative sign.
- Absolute values: $1 + 13 = 14$
- Result: $-14$

Answer: $-14$

---

#### 15. $(-23) + 7$
- Subtract the absolute value of the positive number from the absolute value of the negative number.
- Absolute values: $23 - 7 = 16$
- Since $-23$ has the larger absolute value, the result is negative.
- Result: $-16$

Answer: $-16$

---

#### 16. $25 + (-5)$
- Subtract the absolute value of the negative number from the positive number.
- Absolute values: $25 - 5 = 20$
