Teaching

I’m very well acquainted, too, with matters mathematical,
I understand equations, both the simple and quadratical,
About binomial theorem I’m teeming with a lot o’ news,
With many cheerful facts about the square of the hypotenuse.

—From “The Major General’s Song”, The Pirates of Penzance

I have recorded two mini-lessons for use in teaching combinatorics: a review of sets and a review of functions.
