Sure! Let’s solve each of the integer addition and subtraction problems step by step. The worksheet contains 20 problems, arranged in two columns.
---
Left Column Solutions:
1.
8 + (–6)
→ Adding a negative is like subtracting: 8 – 6 =
2
2.
0 + 10
→ Anything plus zero is itself:
10
3.
(–9) + (–3)
→ Adding two negatives: –9 – 3 =
–12
4.
6 + (–4)
→ 6 – 4 =
2
5.
8 + 1
→ Simple addition:
9
6.
6 + 6
→
12
7.
0 + (–2)
→ 0 – 2 =
–2
8.
(–9) + 4
→ Start at –9, move 4 right: –9 + 4 =
–5
9.
6 + 1
→
7
10.
4 + (–2)
→ 4 – 2 =
2

Right Column Solutions:
1.
2 + 7
→
9
2.
(–9) + 6
→ –9 + 6 =
–3
3.
(–1) + 6
→ –1 + 6 =
5
4.
6 + (–4)
→ 6 – 4 =
2
5.
3 + 5
→
8
6.
(–5) + (–4)
→ –5 – 4 =
–9
7.
(–2) + 8
→ –2 + 8 =
6
8.
(–7) + 3
→ –7 + 3 =
–4
9.
7 + (–1)
→ 7 – 1 =
6
10.
(–5) + 8
→ –5 + 8 =
3

💡 Quick Tips for Integer Addition/Subtraction:
-
Same signs? Add the absolute values, keep the sign.
- Example: (–9) + (–3) = –12
-
Different signs? Subtract the smaller absolute value from the larger one, keep the sign of the number with the larger absolute value.
- Example: (–9) + 4 → |–9| > |4| → 9 – 4 = 5 → sign is negative →
–5
- Adding zero changes nothing.
- Adding a negative = subtracting its positive counterpart.
