This was so nice and clear snd very well broken down. I think she may be destined to be a math proffesor

THANK YOU! The Encryption video and this one, helped me a lot! Really good Explanation!

@guneetsura3178 2 года назад

Amazing job! Helped me with my test practice and cleared my concepts. Thanks for coming up with such videos! Hope to see more in future!

@arthpatel2110 4 года назад

LMAO the best part is, I just learned to find the inverse today and then I decided to watch this video. What are the chances of that?!

@dianeaugustyn3715 4 года назад

One of the best I've seen so far!! I had to watch a dumbed-down video to move up to this, but it was super helpful.

Life savior thax for explaining 7 inverse i am looking for it on web for a long time but finally got here...

@jay-rathod-01 3 года назад

bro just use hit and trial method extended euclidian takes so much time.

@ella1854 2 года назад

how did you know that you had to use 26 in the "7 inverse mod 26" equation?

@harshitagarwal7475 2 года назад

26 letters are there in alphabet which are given values 0-25

what about (4,2) keys?

@aaronlim3268 5 лет назад

4 can't be inverse, hence invalid key

@beckychiang2667 6 лет назад

Awesome video.

@fahadjawed9722 3 года назад

Why we use 7? 7 is the key??

@abdulhalimmire5328 9 лет назад

@mihir469 7 лет назад

Why is 7 inverse not 1/7??

@mucahitkayadan5753 7 лет назад

this inverse is not aritmetic inverse. It is modular inverse.
