Here's another great resource on the topic: https://andrea.corbellini.name/2015/05/17/elliptic-curve-cryptography-…

This [0] was also a very good introduction to elliptic curve cryptography written by a friend of mine in 2015. Highly recommended.

As some others have pointed out, this is very basic stuff, but a good introduction. I have found this series of blog posts [0] as a super useful explanation of ECC that starts with the basics but covers the math and underlying group theory well, building up to an intermediate-level understanding of the matter.

This is a pretty good intro article: https://andrea.corbellini.name/2015/05/17/elliptic-curve-cryptography-…

As nice as it is, integers are not a field (i.e. most of them don't have multiplicative inverses, or 1/n usually isn't integral).
Another good writeup:
