I have a weird mind that occasionally obsesses with some probably trivial math problems. I thought I'd this obsession with the world at large, even if the world isn't ready for it. But this blog isn't really the place for it, so I'm starting a new one:
Stupid Math Tricks, available at a browser near you, or from the sidebar on the right.
Don't worry, when I upgrade Hal to LMDE I'll post all about it right here.
