---

Let's go through each one with explanations.

---

A) 8 + 4 =

Add two positive numbers:
8 + 4 = 12

---

B) 5 + 2 =

Positive + Positive:
5 + 2 = 7

---

C) 9 + (–3) =

Adding a negative is the same as subtracting:
9 – 3 = 6

---

D) 6 – 11 =

Subtracting a larger number from a smaller one:
6 – 11 = –5

---

E) –7 + 5 =

Negative + Positive:
Think: 7 – 5 = 2, but since –7 is more negative, result is –2

–7 + 5 = –2

---

F) 8 + (–3) =

Same as C:
8 – 3 = 5

---

G) –12 + (–4) =

Adding two negatives:
–12 – 4 = –16

---

H) –3 – 5 =

Subtracting a positive:
–3 – 5 = –8

---

I) 10 + (–5) =

Same as 10 – 5:
10 – 5 = 5

---

J) –7 – 3 =

Subtracting a positive from a negative:
–7 – 3 = –10

---

K) –15 + (–15) =

Two negatives added:
–15 – 15 = –30

---

L) –17 + (–6) =

Again, adding negatives:
–17 – 6 = –23

---

M) –12 – 16 =

Subtracting a positive from a negative:
–12 – 16 = –28

---

N) 19 – (–5) =

Subtracting a negative = adding:
19 + 5 = 24

---

O) –13 + 9 =

Negative + Positive:
13 – 9 = 4, but since –13 is bigger in magnitude:
–13 + 9 = –4

---

P) –20 + 20 =

Opposites cancel out:
–20 + 20 = 0

---

Q) 28 – (–11) =

Subtracting a negative = adding:
28 + 11 = 39

---

R) –18 – (–16) =

Subtracting a negative = adding:
–18 + 16 = –2

---

S) –25 + (–8) =

Adding two negatives:
–25 – 8 = –33

---

T) –13 – (–5) =

Subtracting a negative = adding:
–13 + 5 = –8

---

Key Tips:

- Adding a negative is the same as subtracting.
- Subtracting a negative is the same as adding.
- When adding numbers with different signs, subtract the smaller absolute value from the larger and keep the sign of the larger.
- When adding same signs, add and keep the sign.
