Pell Conics
An Alternative Approach to Elementary Number Theory
In this book I would like to present the content of elementary
number theory using an approach based on Pell conics. The idea
is to prepare the readers for more advanced material on elliptic
curves or algebraic geometry at a very early stage. Comments
and corrections are highly welcome.

The second part of this book will discuss the geometric interpretation
of the group law, Pascal's Theorem, group laws on degenerate conics
and singular cubics, Newtons' method and formal group laws, the group
law via the theory of divisors in function fields, and a few other topics.
