Let’s go through each one with explanations.

---

A) 8 + 4 =

Answer: 12
Explanation: Both numbers are positive. Add them: 8 + 4 = 12.

---

B) 5 + 2 =

Answer: 7
Explanation: Simple addition: 5 + 2 = 7.

---

C) 9 + (–8) =

Answer: 1
Explanation: Adding a negative is the same as subtracting: 9 – 8 = 1.

---

D) 6 – 11 =

Answer: –5
Explanation: Subtracting a larger number from a smaller one gives a negative result: 6 – 11 = –5.

---

E) –7 + 5 =

Answer: –2
Explanation: Start at –7 and add 5 → move right 5 units: –7 + 5 = –2.

---

F) 8 + (–8) =

Answer: 0
Explanation: Opposite numbers cancel out: 8 – 8 = 0.

---

G) –12 + (–4) =

Answer: –16
Explanation: Adding two negatives: –12 – 4 = –16.

---

H) –3 – 5 =

Answer: –8
Explanation: Subtracting a positive means moving left: –3 – 5 = –8.

---

I) 10 + (–5) =

Answer: 5
Explanation: 10 – 5 = 5.

---

J) –7 – 3 =

Answer: –10
Explanation: –7 – 3 = –10 (subtracting a positive).

---

K) –13 + (–15) =

Answer: –28
Explanation: Add absolute values and keep the negative sign: 13 + 15 = 28 → –28.

---

L) –17 + 60 =

Answer: 43
Explanation: 60 – 17 = 43. Since 60 is larger and positive, answer is positive.

---

M) –12 – 16 =

Answer: –28
Explanation: Subtracting a positive is like adding a negative: –12 – 16 = –28.

---

N) 19 – (–5) =

Answer: 24
Explanation: Subtracting a negative is like adding: 19 + 5 = 24.

---

O) –13 + 9 =

Answer: –4
Explanation: –13 + 9 = –4 (start at –13, move right 9 units).

---

P) –20 + 20 =

Answer: 0
Explanation: Opposites cancel: –20 + 20 = 0.

---

Q) 28 – (–11) =

Answer: 39
Explanation: Subtracting a negative → add: 28 + 11 = 39.

---

R) –18 – (–16) =

Answer: –2
Explanation: Subtracting a negative → add: –18 + 16 = –2.

---

S) –23 + (–8) =

Answer: –31
Explanation: Two negatives: –23 – 8 = –31.

---

T) –13 – (–5) =

Answer: –8
Explanation: Subtracting a negative → add: –13 + 5 = –8.

🔍 Key Rules to Remember:

- Adding a negative = subtracting: `a + (–b) = a – b`
- Subtracting a negative = adding: `a – (–b) = a + b`
- When adding integers with same signs, add absolute values and keep the sign.
- When adding integers with different signs, subtract smaller from larger and take the sign of the larger.
