Lecture 10a of MATA02: The Magic of Numbers
(https://courses.ywyu.net/MATA02-2022-...)
We spend even more time on Fermat's Little Theorem. We review using it for powers and roots, but then also spend some time stepping through its proof, with an eye towards figuring out how to eventually generalize it.
Apologies for occasionally saying "Fermat's Last Theorem", which I tried to correct when I noticed.
