The grouping symbols most commonly seen in mathematical problems are parentheses, brackets, and braces.
What are grouping symbols in mathematics?
Algebraic grouping symbols — parentheses, brackets, braces, radicals, and fraction lines — show where a group starts and ends, and help to establish the order used to apply math operations. Terms inside a grouping symbol have to be operated upon before they can be acted upon by anything outside the grouping symbol.
What are grouping symbols in order of operations?
The Order of Operations

What is the importance of using group symbol in writing expressions?
Grouping Symbols or Brackets are used to provide clarity in the order of operations, the order in which several operations should be done in a mathematical expression.
