For the translators of this pool.... I wish you all the luck against a huge wall_of_text

Of the things I would have expected under "Elementary Number Theory", Euclid's algorithm is not one of them.

God, I wish my math textbooks looked like this when I went to school.

I guess the joke is that this is like several kinds of advanced mathematics together.

Hoo, didn't expect to see a proof of Euclidean Algorithm on Danbooru. I tried my best to remember how the proof is done, but it's been a while. If there's any mistakes, please correct!

...brb asking my number theory teacher to use this as a textbook...

EDUCATION ON DANBOORU.

SURPRISING, BUT PLEASANT.

too bad we got a hole in the translation.

Hole fixed. The lack of punctuation in that box really impeded the understanding.

Remember, kids, punctuation is your friend!
