What is this blog?

My original post got buried a long time ago, and the explanation in it was less than vague, so I'll try to go into more detail here.

If it wasn't already obvious, this is a cheap little blog where I post interesting math problems, pretty much all of which are contest problems. I try to write the solutions so that they're easy to follow along with, but at the same time they assume that you're familiar with the math needed to solve them.

I write as if I'm trying to explain problems to an audience. However, I hardly share this blog with anyone who would actually read the problems in a way that they were trying to understand them. So then, why bother writing in this way?

Two reasons (there's actually also a third reason that recently became apparent) :
1) They say that if you can't teach something, then you don't understand it. And vise versa. Technically, I'm not actually teaching anyone anything. But by forcing myself to write up these problems in a way that I'm actually explaining them, I can make sure that I truly understand them. But then again, sometimes I only type up problems which I already know I understand, so maybe I'm wasting my time. T_T
2) This is kind of odd, but someday I might want to be a teacher. Now that I think about it, I would probably get frustrated with stupid kids and only want the cream of the crop, so maybe it's not the best choice for me. But if I decide to go down that path, I'll have a little bit of experience teaching a ghost classroom via blog posts.
3) I've recently gotten awfully good at math (obviously I'm not at the IMO level, but I still think I'm pretty good). However, this sudden surge was after the last AMC date, and seeing as I'm in my senior year now, the next AMC's might not be in time for colleges to look at. So this sort of doubles as a way for me to show off my progress.

But, for you, the (non existant T_T) reader, this doesn't have much to do with you. So if you're interested, just go through some of the problems, and maybe you'll learn something!
