Professor Penn, thank you for an awesome introduction to Abstract Algebra. I really like Abstract Algebra. I took this class at the University of Maryland, College Park in the early 1990's.

I saw some Z’s, but I certainly didn’t catch them! Thanks for another entertaining ride.

Why do we care much about associativity? Why study loops more as opposed to groups? When working with real data, generally the order of operations is implied.... Can someone discuss with me?

Thanks for the vids. I'm having trouble proving (Zn, +) is closed.. it seems trivial but the examples I've seen aren't very clear. Looking swole btw... physique and math goals right there
