Follow the Order of Operations "PEMDAS"

•Parentheses (4 + 6) = 10

•Exponents (10)² = 100

•Multiplication 100 x 5 = 500

•Division 500 ÷ 20 = 25

•Addition none

•Subtraction 25 - 18 = 7

Your order of operations is incorrect. It should be 18÷20 not 500÷20. You can't change the order of the equation equation

the answer is 499.1 im pretty sure... 18/20 = 9/10 = .9. so 500 - .9
