So, help me out here: what does the notation -ve and +ve mean? I've seen it used with respect to Descartes's Rule of Signs, I think. It's usually used on polynomials, and I think it has something to do with whether a polynomial is positive or negative in a certain region. Or it might have something to do with the location of roots.
Is it an abbreviation? If so, for what?
Google and AcronymFinder didn't help at all on this one, because it's so short, and I'm wondering if it really is an acronym.
But I think that the ve is shorthand for variation.
Descartes's Rule of Signs counts the number of changes(variations) in signs in both thus counting the possible number of positive and negative roots.

Actually, I was referring more to the point that moderators and admins can mark any thread solved if it's in a forum they moderate. So moderating and administering does have something to do with it. Posting over someone else's post happens so often on this forum that it's really not worth getting worked up over.
