Answer:
Simplification of terms inside the brackets can be done directly. That means we can perform the operations inside the bracket in the order of division, multiplication, addition and subtraction.
Note: The order of brackets to be simplified is (), {}, [].
Example 2: Simplify: 14 + (8 – 2 × 3)
Solution: 14 + (8 – 2 × 3)
= 14 + (8 – 6)
= 14 + 2
= 16
Therefore, 14 + (8 – 2 × 3) = 16.
Example 3: Simplify the following.
(i) 1800÷10{(12−6)+(24−12)}
(ii) 1/2[{−2(1+2)}10]
Solution:
(i) 1800÷10{(12−6)+(24−12)}
Step 1: Simplify the terms inside {}.
Step 2: Simplify {} and operate with terms outside the bracket.
1800÷10{(12−6)+(24−12)}
1800÷10{6+12}
⇒1800÷10{18}
= 1800÷10×18
= 180×18
= 3,240
(ii) 1/2[{−2(1+2)}10]
Step 1: Simplify the terms inside () followed by {}, then [].
Step 2: Operate terms with the terms outside the bracket.
1/2[{−2(1+2)}10]
= 1/2 [{-2(3)} 10]
= 1/2 [{-6} 10]
= 1/2 [-60]
= -30
