Background: In the time of coronavirus, DKU students continue to attend classes! So, we decided we cannot miss out on the opportunity of sharing those videos with you ;)

This class is the continuation of Abstract Algebra classes. It might be useful to know the definition of rings, however, it doesn't require too much background knowledge. If you have any questions, feel free to ask in the comments!

The book we're using is by Theodore Shifrin, however, some content from this and the next lecture is not covered by the textbook.

Enjoy ;)
