Wow, for the first time, I don't feel like an ass about my lack of math skill. I had crap math teachers for the most part, up to high school where my choices were "take the class with the drunk, or the bigot". I LOVE the ideas and concepts in science and physics and all of it, but I struggle at the basics in math, which has never made trying to learn programming easy either. Seriously, thank you for posting this, it makes me feel alot less inadequate about it.
