Hey y'all . . . so, I just found the Fall MAA catalog while roaming around the Internets.
Lots of fun looking new books in there!
I am not presently a member of the MAA but I do get Math Horizon's from my Dad (he works at a small college here in MN) and their website is LOADED with awesome content.
Anyway . . . figured I'd let y'all know about the MAA site if you haven't wandered over there.
I notice they are giving away some full issues of the college mathematics journal.
In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.
