We are asked whether 8^2 - 4 divided by 2 + 2 = 65. 64 - 4 divided by 4 is 60 div by 4 = 15. No, 65 is not correct.
Let's try again, following Order of Operations rules:
Anything within parentheses is done first, followed by exponentiation. After that it's mult. or div., and after that it's addn. or subtr.
8^2 - 4 divided by 2 + 2 = 65 Do 8^2 first; correct result is 64. "-4 div by 2" is -2; adding 2 results in zero. Then we have 64 = 65 (which is false. Are you positive that the original problem included a '65,' not a '64?'
