The role of parenetheses in math is to change the order of operations.

Explanation:

The parenetheses are used in math to change the default order of operations. For example the value of expression

2+2*2

is $6$ $6$ because the correct order is: multiply $2 \cdot 2$ $2*2$ , next add $2 + 4$ $2+4$

If we put the addition in brackets the value changes:

(2+2)*2

The value of this expression is $8$ $8$ because the order is changed. First operation is to add $2 + 2$ $2+2$ (this operation is done first because the expression is in brackets), next is to multiply $4 \cdot 2$ $4*2$
