Really wish these videos did not end 5 years ago. They are very good.

[vigneshjothilingam]

Wow what a explanation... you are also the one that make me love math

[jpdemont]

There are quite a few playlists on YouTube devoted to Modern Algebra but this is the best. Thank you so much for making and sharing this.

[Jkfgjfgjfkjg]

Great videos. I just wish you could produce new videos as fast as my Abstract Algebra course moves...

Thank you

[samchau]

Please make abstract videos on Isomorphisms, Rings and Integral Domains. And more videos on how to get hold of one's intuition for making proofs. Most students suck at proofs and profs seem to think we should be able to do this shit or run after them all day

[soklylorn]

These videos are so helpful.
Thank you very much.

[Mannu_]

Your explanation and your voice both are fabulous.

[karthikaa]

So clear and interesting. I just wish you could produce new videos Abstract Algebra.

[dipankardutta]

it was clear, dats y attractive n not boring . well done .

[juanjaimescontreras]

Not sure if my professor would accept a verbal “ yes it is associative “.

[vismayanm]

It is an really useful video.... thankyou sir 😊

[hitmanDagenius]

So clear and interesting ! thanks a lot for such videos !
Group theory has lot of applications right?
I noticed it has lot of importance in other areas of mathematics . For example, there is an elegant proof of Fermat's Little theorem using abstract algebra !

[michaelturkson]

very very inspiring. thank you so much Sir

Mr. learnifyable thank you very much, but how we can get this book or pdf

[eslamababneh]

Great . Can you make videos about binary operations .please

[ivankristoffergamilla]

In 8:25 why is it groups when you cannot have inverse of 2 it should have a value of -2 right to satisfy the inverse property?

Mr. Learnifyable:

Another fine video on subgroups.  I really like the examples and your teaching style is easy to understand.  Will you be producing videos on cyclic groups, generators of a group/subgroup, cosets, permutation groups, etc. in the near future?

You are a marvelous communicator!

"not just the identity"
So u mean, no trivial subgroups are including the identity?
Sorry I just confused... I hope u noticed

[revanthreddy]

At 7:54 what is it ? Four mod four is zero, I didn't get it.. could you please explain it more clearly 🌝

[tayyabazeb]

Plz how to prove that S4/V4 is isomorphic to s3
