Lorenzo should have added 88 and 66 before subtracting. The order of operations says to add before you subtract.\newline(C)Yes, Lorenzo's work is correct.
  1. Check Calculation: Step 11: Check Lorenzo's calculation from the original expression to Step 11.\newlineOriginal expression: 5×3223+65 \times 3^2 - 2^3 + 6\newlineLorenzo's Step 11: 15223+615^2 - 2^3 + 6\newlineError: Lorenzo incorrectly calculated 5×325 \times 3^2 as 15215^2 instead of 5×9=455 \times 9 = 45.
