An introduction to the Julia language, part 2

I took two years of undergrad algebra. We did use Herstein's text, and Hungerford's, and some random other things that I can't even remember, plus a ream of hand-typed notes from one professor. (And this was the 90s, so typewriters were getting pretty rare by then. He did not use an electric typewriter.) Given that this professor was eclectic enough to refuse to acknowledge daylight savings time, we got to see all sorts of interesting notational issues.
