Parentheses known as Round Brackets are the most commonly used Symbol of Grouping

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
