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.)

I didn't know about the Archimedean Property... Thanks for pointing that out.

Clarity seems to escape me. I don't know why I didn't think of that.

I like this, but at this point in the book, Spivak hasn't covered limits...

comment Proving that $\sqrt{2}+\sqrt{3}$ is irrational
This is clever and very simple. I barely missed this idea. I was trying to do stuff with conjugates, but didn't quite connect the dots.
