Hello CodeForces!

I know this question isn't for this site, but I don't have a better place to ask. What are some good and useful number theory defintions and theorems? I need some for high school competition. I would appreciate if you can help me, at least names or links, no need for declaration and the statement.

Thanks!

Dear Sprdalo,

Thanks for sharing your interest in number theory for high-school students.

The following free legal reference seems to be convenient for your sought educational objectives.

William Stein, Elementary Number Theory: Primes, Congruences, and Secrets, Springer, 2017.

Best wishes.

My teammate created some blog posts to help my university members starting on competitive programming.

It can be too simple if you already study though.
