State and prove a variation on today’s Take-2-or-1 Theorem, but where players can take 1 or 3 stones. Use as a model the proof from class notes and/or my writeup.

Tasks:

Note: Friday, March 24th will be a recorded lecture (so no need to attend class); you will find it on this website and view it over spring break at your leisure.

Wednesday is a proof quiz. It will be a proof by contrapositive. Examples can be found in Chapter 5 of Hammack. Do some exercises from there as practice.

Because of spring break, you will have until April 7th to do a logic study sheet in order to request a logic grade improvement. Solutions to the quiz can be found in the “Materials Archive” page as usual.
