I'm a math/programming teacher and freelance programmer. My first language was Scheme, and I have a major soft spot for functional programming. I read SICP every year and do all of the exercises (so I'm pretty good at hw-type problems.)

P.s. I mentioned I tried that approach. I couldn't get anywhere with it. Blue, can you expand on the proportionality arguments? I tried using similar figures to get proportions, but I couldn't show any helpful ones.
