How to do math problems in parentheses. Now lets solve the other parentheses. Lets try another example of solving equations with parentheses. Simplify 3 2 1 32 23 The innermost parenthetical is the exponent stuff inside the parentheses.
Rewrite the equation after each step. To solve an equation that has parentheses distribute to get rid of the parentheses then follow order of operations to simplify the rest of the equation. In this problem we only have one set.
