Adding Integers Worksheets - Free Printable

Sure! Let’s solve each of the 12 integer addition problems step by step, using the rules provided at the top of the worksheet.

Adding Rules Recap:

- Positive + Positive → Add and keep positive sign.
Example: `5 + 4 = 9`
- Negative + Negative → Add absolute values and keep negative sign.
Example: `(-7) + (-2) = -9`
- Negative + Positive (or vice versa) → Subtract the smaller absolute value from the larger one, and use the sign of the number with the larger absolute value.

Now let’s solve each problem:

---

1. -106 + 40

- One negative, one positive → subtract: `106 - 40 = 66`
- The larger absolute value is 106 (negative), so result is negative.
✔ Answer: -66

---

2. 13 + -30

- Same as `13 - 30` → subtract: `30 - 13 = 17`
- Larger absolute value is 30 (negative), so result is negative.
✔ Answer: -17

---

3. 57 + -15

- Same as `57 - 15 = 42`
- Larger absolute value is 57 (positive), so result is positive.
✔ Answer: 42

---

4. 26 + 66

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

---

6. 17 + 54

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

---

7. -9 + -1

- Both negative → add absolute values: `9 + 1 = 10`, keep negative sign.
✔ Answer: -10

---

8. -29 + -73

- Both negative → add: `29 + 73 = 102`, keep negative sign.
✔ Answer: -102

---

9. 124 + -18
