# 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.
