I looked at this video and was surprised that it didn't have more views! Out of all the group theory videos that I've searched for to help me in my Algebra class, this series has been by far the most helpful. You explain concepts so engagingly and make them easy to understand without simplifying the content. I appreciate the amount of dedication you put into these videos- thank you and keep it up!
