# Definition of Parentheses

**Parentheses** are round brackets used to group parts of a mathematical equation or expression together, and to tell you which operations should be performed first.

For example, in the expression

\( (6 - 3) \times (2 + 5) = 3 \times 7 = 21,\)

the parentheses group \(6\) and \(3\) together, and \(2\) and \(5\) together. They also indicate that we need to evaluate \(6 - 3\) and \(2 + 5\) first, before we evaluate the rest of the expression.
