Perform Addition Operation: First, we need to perform the operation inside the parentheses. We add the two numbers 7 and 2 together.Calculation: 7+2=9
Multiply by 10: Now that we have the sum of the numbers inside the parentheses, we multiply that result by 10.Calculation: 9×10=90
Check for Errors: We check for any possible math errors in the previous steps. Both addition and multiplication are straightforward, and the calculations are correct.
