Sure! Let’s solve each problem on the
“Integer Addition and Subtraction” worksheet step by step.
We’ll use basic integer rules:
- Adding two positive numbers → add normally.
- Adding two negative numbers → add their absolute values, keep the negative sign.
- Adding a positive and a negative → subtract the smaller absolute value from the larger one, and keep the sign of the number with the larger absolute value.

Left Column:
1.
8 + (-6)
→ 8 - 6 =
2
2.
0 + 10
→ 0 + 10 =
10
3.
(-9) + (-3)
→ Add absolute values: 9 + 3 = 12, keep negative →
-12
4.
6 + (-4)
→ 6 - 4 =
2
5.
8 + 1
→ 8 + 1 =
9
6.
6 + 6
→ 6 + 6 =
12
7.
0 + (-2)
→ 0 - 2 =
-2
8.
(-9) + 4
→ 9 > 4, so 9 - 4 = 5, keep negative →
-5
9.
6 + 1
→ 6 + 1 =
7
10.
4 + (-2)
→ 4 - 2 =
2

Right Column:
1.
2 + 7
→ 2 + 7 =
9
2.
(-9) + 6
→ 9 > 6, so 9 - 6 = 3, keep negative →
-3
3.
(-1) + 6
→ 6 > 1, so 6 - 1 = 5, keep positive →
5
4.
6 + (-4)
→ 6 - 4 =
2
5.
3 + 5
→ 3 + 5 =
8
6.
(-5) + (-4)
→ 5 + 4 = 9, keep negative →
-9
7.
(-2) + 8
→ 8 > 2, so 8 - 2 = 6, keep positive →
6
8.
(-7) + 3
→ 7 > 3, so 7 - 3 = 4, keep negative →
-4
9.
7 + (-1)
→ 7 - 1 =
6
10.
(-5) + 8
→ 8 > 5, so 8 - 5 = 3, keep positive →
3
