The approach you took at the beginning of the explanation is what made this video different from all others. Sometimes persons start with the abstract and then lead to the examples by which time the viewer is completely confused. However, you took the difference approach and i understood perfectly. Thank you.
Wonderful.... Video helped me a lot in understanding the topic.... Thank you sir... For...providing Sach a easy way to understood these tough topics of math's ....
Excellent series. Thank you. And thank you especially for noting that many authors and mathematicians are sloppy with their notion when they fail to include the binary operator in the group name or definition. That confused me for so long.
I have a question on 11:00 you said it's not a group because zero is part of the set but why is the first one considered a group if zero is also part of the set and zero doesn't have an inverse, so doesn't that mean it shoudn't be a group?
THANK YOU VERY MUCH. But i think IS A GROUP. At times the inverse of an element can be the element itself mostly from the cayley's table But if am wrong you can help me too
Does this mean that when we consider a group of the set of rational numbers we consider subsets as well? In the example rational numbers under addition: if we add (1/2 + 1/2) we get an integer. Is it correct to say that the set of integers is a subset of the rational numbers therefore it does not violate closure under addition?
bizarre? think about a civilization that doesn't know abstract algebra. Would throw us back technologically into the early twentieth century, I would guess

Can we just take a moment to appreciate the fact that this course is accessible to all, completely free and easy to understand!

The way the topic has been explained, the approach, is great. You made it so easy to understand. Appreciable.

Thank you very much for this! I am in my first week of Linear Algebra in college and this was very helpful.
Excellent series. Thank you. And thank you especially for noting that many authors and mathematicians are sloppy with their notion when they fail to include the binary operator in the group name or definition. That confused me for so long.
Thank you for the kind words!
@learnifyable I think lack of a/0 doesn't disuqallify that from being a group, there is just an exception.
Good 1,keep up the good work,short and succinct, and undoubtedly the best
Thanks! I'm glad I could help.
soo helpful thanks

Great video. Very helpful in helping me cement the definition of a group. Thank you!
Can you make a video on lattice as soon as possible cuz O am having my exams soon and your video is gonna save my life
What about:
a,b elements of N.
a*b= a^b
Is that a group????
This is so succinct and easy to learn from

Superb!!

But if am wrong you can help me too
is a group but you have to exclude 0 from the set.
Subscribed!!!!!!
Thank u very much sir.
I understood each nd every concept through ur video
Wow man, you're pretty much just as good as khan academy, damn
tq tq tq tq tq tq so much
very helpful keep up the good work...!!
Sir z(i) what type of element in this group
Very lucid. Thanks
You save my life 💓
Can't get any clearer than this :)
this reals helped me...
thank you
+mohamud kediye No problem! :)
In the Math history, the real number with operation + and operation * came first, or the Group theory came first?? just curious! Thanks!
Thank u sir. I finally understand.
cset subtest 1 prep videos? please:))))
Nice. easy to understand, thank you so much

Yes please
Good stuff.
Thank you.
This was soooo helpful wow
what book do you use teacher , please
I recommend:
A First Course in Abstract Algebra by Fraleigh
Algebra Pure & Applied by Papantonopoulou
A Book of Abstract Algebra by Pinter
@@learnifyable thanks
Great explication.
Thank you sir
that really helped. thank you so much.
thank you so much.. this is a great help for me.
thank you so much u have help me a lot
Amazing
Thanks
Very Nice #drupasanapahujataneja
I love math but honestly, I am not interested in abstract algebra. This is truly bizarre.

@@guidofeliz8384 abstract algebra is usually taught in the first two years of undergraduate maths education
It’s very meta

1. I made that comment 4 years ago.
2. What is meta?
my quiz will start after 1 hour.. wish me luck
