It's a shame that this last video was 2 years ago. These videos have been very helpful for me. If you would start making videos again could you please do one about arithmetic and geometric sequences and series?

[Oafishe_]

I hope you're doing well paul. Your my new math teacher now :)wishing you'd make more videos

[crisllerena]

Thank you a lot, I've trying to understand what mod is for a couple days, and only after watching your videos I understood. Great video!!

[APare-bxir]

paul. buddy. you're saving my life here. i will marry your first born daughter as a way of showing my eternal gratitude to you and your bloodline.

[alial-lami]

actually comeback though, ive been looking for 2 hours and this is the best video i found

[aydenmudge]

please make a parrt 6 to the cryptography playlist!!!

[ralyngarcia]

Thanks for this Paul, clear explanation 👍🏻

Thank alot👏🏻

Please if you can do a vedio about:

Modular inverses

Euler's Totient function

Modular exponentiation

Bezout's identity


We appreciate your effort

Thumps up 👍🏻

WHY CAN'T YOU BE MY MATH TEACHER IN


Also do you have a finance section?

[jonatansvensson]

This series is going to help my math IA immensly.

I became a fan of U In maths now U hav stpd putin vid for 5 yrs I interested in ur maths and I like to continue. Plz Paul bro

I've noticed something: If you number each modular repetition on a number line (0, 1, 2, 0, 1, 2... for mod 3), starting at 0, q represents which repetition n will fall under.

East or West, videos with white backgrounds and human handwriting are the best !!!

[accidentalGamer]

Man, you should be my math teacher in high school, I would have aced in maths !!

[thetaiman]

Thanks Paul, hope u come back to youtube

[mr_cod]

The Next Vid in the Playlist is a famous tiktok song that i never knew it's origin xD. Thanks for the Videos too

[ethanchewy]

Thanks so much! This video was super helpful!

[redtedredeemer]

I don't suppose you have any videos on finding the order of an element in in a modulus group?

[dscruiter]

shouldn't it be 8*3 (mod 3) = ((8 mod 3) * (11 mod 3)) mod 3? or am I missing something?

Are you still alive i need you your the best teacher
