Math worksheet for practicing addition of negative numbers with colorful title and blank spaces for answers.

Let's solve each of these addition problems involving negative numbers step by step. The key rule to remember is:

- Adding a negative number is the same as subtracting a positive number.
- When adding two negative numbers, add their absolute values and keep the negative sign.
- When adding a positive and a negative number, subtract the smaller absolute value from the larger one and keep the sign of the number with the larger absolute value.

1. $-4 + 3$

We are adding a negative and a positive:
- $|-4| = 4$, $|3| = 3$
- $4 - 3 = 1$, and since $-4$ has the larger absolute value, the result is negative.
- So, $-4 + 3 = -1$

✔ Answer: -1

---

2. $8 + (-10)$

Same as $8 - 10$:
- $10 - 8 = 2$, and since $-10$ has the larger absolute value, result is negative.
- So, $8 + (-10) = -2$

✔ Answer: -2

---

3. $-3 + (-5)$

Two negatives: add absolute values and keep negative sign.
- $3 + 5 = 8$, so $-3 + (-5) = -8$

✔ Answer: -8

---

4. $11 + (-7)$

Same as $11 - 7 = 4$

✔ Answer: 4

---

5. $6 + (-1)$

Same as $6 - 1 = 5$

✔ Answer: 5

---

6. $-9 + (-2)$

Add absolute values: $9 + 2 = 11$, both negative → result is $-11$

✔ Answer: -11

---

7. $-12 + 5$

Same as $-12 + 5$: $12 - 5 = 7$, and since $-12$ has larger absolute value, result is negative.
So, $-12 + 5 = -7$

✔ Answer: -7

---

8. $(-2) + (-4)$

Add absolute values: $2 + 4 = 6$, both negative → $-6$

✔ Answer: -6

---

9. $7 + (-13)$

Same as $7 - 13 = -6$

✔ Answer: -6

---

10. $-6 + 8$

Same as $8 - 6 = 2$, and since $8$ is positive and has larger absolute value, result is positive.

✔ Answer: 2
