First off, the reason I referred to the website is because I thought we were not supposed to do homework questions for some one on this forum. Yes I did know how to solve the problem, but instead of just showing them how to answer this problem, I thought maybe since it was their homework, they are doing more problems like that one. Therefore, the website would be more help then for me to just show them how to work that specific problem.
And the reason I said "Its not my purpose to figure out why they are asking, but only to help", is because before your edit you said something like anyone who can fill out the information to become a member of Help Desk should be able to do this problem. Well that may be true, but I know there are times I have a bit of a "blonde moment" and can't figure out a simple problem for the life of me. But what I meant by that statement was just that I don't know if they are just having a hard time with math or even if they too were just experiencing a "blonde moment". Still I don't think there is any reason not to help someone who is in this situation regardless of why the are asking the question.
