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.

The answer will be different depending on which way the expression is evaluated.

When to use brackets and grouping symbols in math?
Grouping symbols in math expressions include: 1. Parentheses 2. Brackets: 3. Braces: All grouping symbols tell you, “Do this first!”. Parentheses are used in math to show a part of a math expression or equation that must be solved first, before any other calculations are done.
