The first step for solving this expression is to add the numbers in the first parenthesis. 7.2((9 - 2) + 2.5) Subtract the numbers in the parenthesis found inside the other parenthesis. 7.2(7 + 2.5) Add the numbers in the parenthesis. 7.2(9.5) Now multiply the two numbers together to get your final answer. 68.4 This means the expression (4 + 3.2) × ((9 − 2) + 2.5)is equal to 68.4.
