Oooh, that does help. It also tells me that I need to go back to the while loop/for loop sections to get a better handle on how the two are constructed and the differences between them.

Yeah, I'm pretty sure at least half of my issues with this is the math; I got through AP Calc BC by the skin of my teeth in high school, six years ago, and I haven't looked at anything other than statistics since then. Thank you again!
