So this simplifies to 6 times 9 which of course is equal to 54. 1 3 36 9 2 2. Parenthesis in math are used to group important things together so you always do them first.
First per the PEMDAS rule we must simplify whats in the parentheses.
9 12 2 5 1 perform within parenthesis 9 10 5 1perform multiplication. Second evaluate the exponents. To fix the problem have the student try using parentheses around the denominator to tell the calculator to simplify the 7 3 first. I know how to perform mixed operations with parenthesis exponents multiplication division addition and subtraction.
