Question

What do parentheses mean in math?

Answer 1

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` because the correct order is: multiply `2*2`, next add `2+4`

If we put the addition in brackets the value changes:

(2+2)*2

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