Evaluate Expression: Joey starts by evaluating the expression 97−3+53÷25×2×32. He calculates 53 as 125 and 32 as 9.
Calculate Exponents and Division: Joey then divides 125 by 25 to get 5, and continues with 5×2×9.
Perform Multiplication: Joey multiplies 5 by 2 to get 10, and then multiplies 10 by 9 to get 90.
Complete Addition and Subtraction: Joey then adds 90 to 94 (97−3). He should have subtracted 3 from 97 first, then added 90.
