**Question: 1**

Simplify

3 – (5 – 6 ÷ 3)

**Solution:**

3 – (5 – 6 ÷ 3)

= 3 – (5 – 2)

= 3 – 3

= 0

∴ 3 – (5 – 6 ÷ 3) = 0

**Question: 2**

Simplify

– 25 + 14 ÷ (5 – 3)

**Solution:**

-25 + 14 ÷ (5 – 3) = – 25 + 14 ÷ (2)

= – 25 + 14/2

= –25 + 7

= –18

∴ – 25 + 14 ÷ (5 – 3) = – 18

**Question: 3**

Simplify

**Solution:**

**Question: 4**

Simplify

**Solution:**

**Question: 5**

Simplify

36 – [18 – (14 – (15 – 4 ÷ 2 × 2))]

**Solution:**

36 – [18 – (14 – (15 – 4 ÷ 2 × 2))]

= 36 – [18 – (14 – (11 ÷ 2 × 2))]

= 36 – [18 – (14 – 11/2 × 2))]

= 36 – [18 – (14 – 11)]

= 36 – [18 – 3]

= 36 – 15

= 21

∴ 36 – [18 – (14 – (15 – 4 ÷ 2 × 2))] = 21

**Question: 6**

Simplify

45 – [38 – (60 ÷ 3 – (6 – 9 ÷ 3) ÷ 3)]

**Solution:**

45 – [38 – (60 ÷ 3 – (6 – 9 ÷ 3) ÷ 3)]

= 45 – [38 – (20 – (6 – 3) ÷ 3)]

= 45 – [38 – (20 – 3 ÷ 3)]

= 45 – [38 – (20 – 1)]

= 45 – [38 – 19]

= 45 – [19]

= 26

∴ 45 – [38 – (60 ÷ 3 – (6 – 9 ÷ 3) ÷ 3)] = 26

**Question: 7**

Simplify

**Solution:**

= 23 – [23 – (23 – (23 – 0))]

= 23 – [23 – (23 – 23)]

= 23 – [23 – 0]

= 23 – 23

= 0

**Question: 8**

Simplify

**Solution:**

= 2550 – [510 – (270 – (90 – 150))]

= 2550 – [510 – (270 – (–60))]

= 2550 – [510 – 330]

= 2550 – [180]

= 2550 – 180

= 2370

**Question: 9**

Simplify

**Solution:**

**Question: 10**

Simplify

**Solution:**

**Question: 11**

Simplify

**Solution:**

**Question: 12**

Simplify

[29 – ( – 2)(6 – (7 – 3))] ÷ [3 × (5 + ( – 3) × (-2))]

**Solution:**

[29 – (-2)(6 – (7 – 3))] ÷ [3 × (5 + (- 3) × (- 2))]

= [29 – (- 2)(6 – 4)] ÷ [3 × (5 + (3 × 2))]

= [29 – (-2)(2)] ÷ [3 × (5 + 6)]

= [29 + 4] ÷ [3 × 11]

= [33] ÷ [33]

= 1

∴ [29 – (-2) (6 -(7- 3))] ÷ [3 × (5 + (- 3) × (-2))] = 1

**Question: 13**

(i) 9 (2 + 5)

(ii) 12 ÷ (1 + 3)

(iii) 20 ÷ (7 – 2)

(iv) 2 × 3 – 8

(v) 40 ÷ [1 + (9 + 10)]

(vi) 2 × [(19 – 6) – 1]
