This has got to be the best introduction to modular math I’ve ever seen. Straight to the point and by someone that knows what they’re talking about. I’ve noticed that the people who break it down like this are really good at what they do and the people that try to sound “smart” don’t really understand what they’re trying to teach. Thank you.

It took me a solid hour of scratching my head then I found your video series and understood it all in 10 minutes, thanks a lot.
Bruh I've been scratching my head for ages.
3 and 5 have the same value when we are dealing with mod 2 . great explanation sir . HATS OFF!!!

So much easier than the other videos explaining the same thing. Thank you!
Thank God for people like you that can simplify and teach knowledge. Keep it up, you are a blessing to human kind.
Wow, just amazing tutorial. You explained the basic modular arithmetic in the most clear way possible.
man you really made my life easy after watching this video. all the best for you and please do not stop! the world really needs you
Thank you so much! You saved me! I was sitting in discrete math class scratching my head like, "What the hell is this?!?" Most videos I found seemed like they were for people who already understand what is going on. I needed someone to teach me like am learning a new language for the first time. You explained it to me perfectly and now I understand. Thank you!!!
OMG!!! thank you so much!! In only less than 5 min I got what I had been trying to understand with my book for over an hour!!!! :D
Excellent!! Best description I’ve ever seen for modulo math.
This was very helpful, thanks! I've been lost on this stuff for about a month in my class.
Thanks for the tutorial! I attended a lecture about modulo arithmatic and the lecturer managed to make such an easy to undestand topic appear to be rocket science
Coming here to learn modulo after 6years of you posting it and learning it under a few minutes. Thanks a lot for breaking it down
Thank you so much for providing this! It's a big help!
My textbook absolutely SUCKS at explaining this topic.
I did never think of modular this way. Very good explanation.
Standing Ovation bro, bloody good explain. Thank you.
I can never thank you enough for this video, it just saved me before my final!!!! Thank you!
Best explanation I've ever seen. Thanks you so much.
That number line changed how I understand modulos. Thanks!
thank you for explaining it in such simple terms, that really helped me understand this.
This video is excellent. Thank you for explaining this so clearly!
Wow! The modular Arithmetic can be a nightmare but this congruence topic was explained in the most simple way that I have seen.
Very nice ...thanks for posting this👍
Best video on UA-cam about modular arithmetic thank you sir
you taught this way better than my professor ever could from a 90 min lecture in under 5 minutes!! thank you!!!!!
I've watched many videos and went to many websites to just understand what is mod. Honestly I didn't understand anything till Ive seen ur video. I think it's fair to say you have the best modular arithmetic intro video
You are a king for this.
Great video. After looking on Google at explanations of modular arithmetic, to no avail, you're video has helped greatly. Cheers.
literally the first video I have liked on youtube ever
Thank you so much! being an online college student was confusing but this video helps a lot when it comes to cryptography
Finally! Thanks for this video. You explained it clearly than my Prof
the values in the mod space can be thought of as a circle made up of m-1 terms
so 14%12 like a 12hr clock and so you send up on 2 after you move 14 spaces
Very clear explanation. Thanks!
Did not need to watch another video after this. Thanks a million
Thanks. Only explanation where it clicked for me
THIS SAVED MY LIFE THANK U
I cannot pass here without let my point of view about the the greatest video i've not seen before! I'm i'm learnig from Mozambique
I know I am 8 years late but this helped so much!!!! You have a way of explaining really well.
Good teaching. Thanks from Texas!
So easy to understand, thanks for the intro
Many videos are complicated and i cannot understand them properly but in this video i understand it quickly. Thank youuu, keep it up:))
The best intro to modular arithmetic
Best Introduction for the Modular Arithmetic
Beautiful explanation. Thank you very much!
Wow, looked so much until I found this. gr8 intro !!
Brilliant video, this is really easy to understand.
Thank you so much
it helped me with programming
Amazing jop, I am taking cs 70 at Berkeley and this has made my life 10000 times easier
Great job! Finally it makes sense to me
Thank you I didn't know cryptography and now I know it and I know that it's very cool...
Thank you again!
awesome video once again. such a simple explanation!
Amazing explanation, thank you!
Thanks so much. Very clear video.
Thank you! Your explanation was so much easier than my course material.
Actually your course material is hard
This helped me a lot! Worked for me really well! Thanks!
Very easy to understand sir.
Thanks a lot
Finally I understand. Thank you!
Damn lesson 2 the one I need
this the simplest explanation and I love it 😍
Your video make me understand modular arithmetic.
Thanks a lot. Finally it makes sense.
thanks for teaching mod it was really helpful
WOW!!!!!I can sleep with a smile ,Finally
Wow i can't believe this is so easy now i realize thank you
This explanation is fantastic
Thanks for this video! Great explanation :)
Great tutorial thank you! Finally I understand :D
Thankyou great introduction.
The best explanation so far. I think it would be better if we could change the symbols and wrote "mod 2" or simply 2 above the congruence symbol. That way things would be much clearer.
This helped me alot neat clean approach explanation this was helpful thankyou ❤️
Sweet ...this is what I was looking for...why it is made difficult
Thx man
I really like your video simple and easy to learn
I think you just got one more subscriber.
Helpful for my math master sessions. Thank you!🎉🎉🎉🎉🎉🎉
Best ever. Thanks.
just subscribed! amazing video explained so well
ur explaining is much more easier than fricking 2hs annoying ass class. thanks.
Easy to understand thanks
Great explanation!
Directionality is fascinating.
Good work you have really explain well have now understand
Thx. A great video. I understand it now!:)
Amazing!! Do you know where I can find the Montgomery modular multiplier explanation? Many thanks
Great video
Thank you
Good introduction!
Супер. Наконец-то стало понятно что за модули блин тут используются.
Loco alto video, corta y al pie. Gracias
Loved it!
You are amazing!!!!
Understood in the first go thanks to you
That's fantastic! Thanks for checking out this lesson! I wish you the best in your studies.
Brilliant!
helped for university exam,thanks you sir.
is 5 congruent to 1 in mod 2 also or just 3? also thx for the explanation
Thank you!!! Really helped.
The numbers you have specified as mods's (For Example: mod(2)= {0,1}) are actually the remainders of the division done. 5/2's remainder is 1, that is why we place a 1 on top of it.
Excellent
Good work .
The wikipedia page on this is a good read. Think of it like a clock, we have 24 hours, but just 12 on an analog clock, so we would say its 5 o'clock, but it could be 05:00 or 17:00, thus 5 and 17 are congruent in mod 12. And thus AM/PM etc etc... You basically create an imaginary limit to infinity where numbers start looping around; like when we say 48 hours or 72 hours, we know how many days that are, because we only have 24 hours in a day, thus 48 hours has to be 2 days. So for example 14 is congruent to 6 in mod 8, because we start counting again at 8.
I'm studying for my CISSP cert and the book was terrible in explaining this, thank you for this!!
First of all ,thank you for this helpful videao,I would like to ask ,if we can do the same process for the rational numbers ?thanks
So helpful!
I thought modular arithmetic was a rocket 🚀 science until I found your video. Now, modular arithmetic is easy peasy like drinking water 😆. Top man, thanks a lot
