Knights, Knaves, and Propositional Logic [Discrete Math Class]

This video is not like my normal uploads. This is a supplemental video from one of my courses that I made in case students had to quarantine. I decided that it might be of general interest for people wanting to learn about propositional logic (mathematical propositions, logical connectives - "and", "or", and "not", truth tables, logical equivalence, and the DeMorgan's laws) and one way that they can be used to solve classic Knights and Knaves problems. Note that this video is part of a series kept in a playlist called [Discrete Math Class]:    • Discrete Mathematics Course   If you like this video, consider subscribing to my channel and let me know in the comments if you'd like to see more like this. This textbook for the course is the open-source textbook by Oscar Levin: http://discrete.openmathbooks.org/dmo...
