This is a video series about basic abstract algebra and group theory. We will keep it basic so that anyone can follow the videos.

This is the twelfth video in the series. We look more at some elementary number theory and connect it to group theory.

  • Cool

    But you are still writing 7! and 1! (seven factorial and one factorial)

    Why conflate the issue with ambiguous notation?

  • @TraleeFair Nah, I am just being way too excited!!!! :)

  • 5/6 = 0 rem. 5 yes, but does -1/6 simply have remainder 5? (I am taking nothing for granted here!) I think when dealing with sets generated by modulus arithmetic there is an issue of |n| to be addressed, or have I missed something?

  • @farfromtheland -1 is congruent to 5 modulo 6, yes. Congruence is also defined for negative numbers.

  • Love these vid clips. Please, keep them coming. :thumbup:

    I know that these vid clips are overviews of fundamental concepts in Basic Algebra. Have you thought about vid clips that actually walk through specific proofs? One vid clip per proof?

    Will you be covering Rings, Fields, Galois Theory? I HOPE SO! :thumbup:

  • Thank you.

    I am not sure how far I will push this basic abstract algebra series, but maybe I will do a series with more advanced topics. If I have an audience, I guess I will continue to define rings and fields too.

    I have thought about making videos with specific proofs, yes. I have done a few, but I guess as the topic gets more advanced, I have to dedicate a whole video to certain proofs.

  • Normally I've got the attention span of a goldfish, but I find myself on Part 12.

  • Thnx! Your videos are great (and music too ;)

  • These videos are one of youtube's best kept secrets. Every abstract algebra student should watch your videos! Keep up the great work! The world needs more people like you! Thank you so much!

  • Please do include more advanced stuff like rings and fields, I really love these clips! TKS~
