Definition of Parentheses
- The symbols “(” and “)” are called parentheses and are generally used in grouping.
More about Parentheses
- The singular form of parentheses is known as parenthesis.
- Parentheses are used to denote modifications to normal order of operations.
- Parentheses are also called round brackets, curved brackets, oval brackets, or just brackets.
Example of Parentheses
- The value of the expression 5 × 8 + 4 is 40. But if we use the parentheses with the same expression by grouping (8 + 4), i.e. 5 × (8 + 4), the value of the expression will be 60 as the order of operation gets changed in this case.
Solved Example on Parentheses
What is the value of the expression (12 + 4) - 4?
Correct Answer: C
Step 1: The operations within the parentheses should be performed first.
Step 2: (12 + 4) – 4 [Original expression.]
Step 3: = 16 - 4
Step 4: = 12
Step 5: So, the value of the expression is 12.
