Exercise 9(A)
(Using BODMOS)
1. 19 – (1 + 5) – 3
Solution:
Given
19 – (1 + 5) – 3
On further calculation, we get
= 19 – 6 – 3
= 19 – 9
= 10
2. 30 × 6 ÷ (5 – 2)
Solution:
Given
30 × 6 ÷ (5 – 2)
On further calculation, we get
= 30 × 6 ÷ 3
= 30 × 2
= 60
3. 28 – (3 × 8) ÷ 6
Solution:
Given
28 – (3 × 8) ÷ 6
Calculating further, we get
= 28 – 24 ÷ 6
= 28 – 4
= 24
4. 9 – [(4 – 3) + 2 × 5]
Solution:
Given
9 – [(4 – 3) + 2 × 5]
We get
= 9 – [1 + 10]
= 9 – 11
= – 2
5. [18 – (15 ÷ 5) + 6]
Solution:
Given
[18 – (15 ÷ 5) + 6]On further calculation, we get
= [18 – 3 + 6]
= 18 + 3
= 21
6. [(4 × 2) – (4 ÷ 2)] + 8
Solution:
Given
[(4 × 2) – (4 ÷ 2)] + 8On further calculation, we get
= [8 – 2] + 8
= 6 + 8
= 14
7. 48 + 96 ÷ 24 – 6 × 18
Solution:
Given
48 + 96 ÷ 24 – 6 × 18
We get
= 48 + 4 – 6 × 18
= 48 + 4 – 108
= 52 – 108
= – 56
8. 22 – [3 – {8 – (4 + 6)}]
Solution:
Given
22 – [3 – {8 – (4 + 6)}]
On calculating further, we get
= 22 – [3 – {8 – 10}]
= 22 – [3 + 2]
= 22 – 5
= 17
9. 34 – [29 – {30 + 66 ÷ (24 –
Solution:
Given
34 – [29 – {30 + 66 ÷ (24 –
On further calculation, we get
= 34 – [29 – {30 + 66 ÷ (24 – 2)}]
= 34 – [29 – {30 + 66 ÷ 22}]
= 34 – [29 – {30 + 3}]
= 34 – [29 – 33]
= 34 – [-4]
= 34 + 4
= 38
10. 60 – {16 ÷ (4 × 6 – 8)}
Solution:
Given
60 – {16 ÷ (4 × 6 – 8)}
On further calculation, we get
= 60 – {16 ÷ (24 – 8)}
= 60 – {16 ÷ 16}
= 60 – 1
= 59
11. 25 – [12 – {5 + 18 ÷ (4 –
Solution:
Given
25 – [12 – {5 + 18 ÷ (4 –
By calculating further, we get
= 25 – [12 – {5 + 18 ÷ (4 – 2)}]
= 25 – [12 – {5 + 18 ÷ 2}]
= 25 – [12 – {5 + 9}]
= 25 – [12 – 14]
= 25 – [-2]
= 25 + 2
= 27
12. 15 – [16 – {12 + 21 ÷ (9 – 2)}]
Solution:
Given
15 – [16 – {12 + 21 ÷ (9 – 2)}]
On further calculation, we get
= 15 – [16 – {12 + 21 ÷ 7}]
= 15 – [16 – {12 + 3}]
= 15 – [16 – 15]
= 15 – 1
= 14
