document.write( "Question 298322: I need your help with an order of operations problem. First, I would like to state that I tried to work the problem, but was unable to come up with an answer. I know that the order of operations follows this list; parentheses(1), exponents(2), multiplication(3), division(4), addition(5), and subtraction(6). Using this knowledge has helped me break the problem down somewhat, but not completely.\r

document.write( "I can deduce that the problems in the parentheses must be evaluated first, however, I'm not quite sure how to go about this. By combining like terms, I can see that 18x would combine with 3x, and 216 would combine with 36. However, they problems do not provide me with a classic distributive property solution. \r
