| Parentheses Parentheses | Braces | Square Bracket | Explanation
Parentheses are the most commonly used Symbol of Grouping. Parentheses are denoted with the symbol "( )". Parentheses are also known as Round Brackets. In a problem, where there are more than one type of brackets, Parentheses are the first one to be solved.
Following are some examples which shows the working of Parentheses
Example 1 = Solve 20 + (1 + 44)
Answer = Firstly, solve the values in the parentheses. and we get;
= 20 + 45 = 65
Example 2 = Solve (5 + 50) - (20 - 10)
Answer = Firstly, solve the values in the parentheses. and we get :-
= (55) - (10)
Now, here we have negative sign(-) in front of the bracket, so, sign of the value inside the bracket will change and we get;
= 55 - 10 = 45
Example 3 = Solve (4 + 16) - (5 - 10)
Answer = Firstly, solve the values in the parentheses. and we get :-
= (20) - (-5)
Now, here we have negative sign(-) in front of the bracket. So, when we open the brackets, sign of the value inside the bracket will change and we get;
= 20 + 5 = 25
Example 4 = Solve 5 (4 + 2) - (14 ÷ 2) + (3 × 5) + 10
Answer = Firstly, solve the values in the parentheses. and we get :-
= 5 (6) - 7 + 15 + 10
Since, no sign is there between 5 and (6), so it written as:
= 5 × 6 - 7 + 15 + 10
Now, apply the rule of BODMAS and we get:
= 30 - 7 + 25 = 55 - 7 = 48
