OpenStudy (texaschic101):

72 - 3 * (5 - 2) 2 -- parenthesis first 72 - 3 * 3 * 2 -- multiplication starting left and moving right 72 - 9 * 2 72 - 18 54 ===> your answer unless the 2 on the end was supposed to be squared ??

OpenStudy (anonymous):

72 - 3 * (5 - 2) ^2 -- parenthesis first 72 - 3 * 3^2 -- exponents next 72 - 3 * 9 -- multiplication next 72 - 27 -- subtraction 45 ===> your answer
