The book is an introduction to the theory of algebraic numbers. The basic concepts and ideas of this theory are set out in it in connection with the farm theorem. The reader must see that their appearance is not accidental, but is dictated by the logic of solving a specific problem. One of the goals of the book is to convince the reader in the depths and complexity of the problems related to the theorem of the farm, and in the complete futility of the search for its elementary evidence.

The presentation in the book is concentric, so that the reader, even with minimal preparation ( For example, a schoolboy), could learn the main ideas.

The book is intended for high school students (in its first chapters), students, teachers and all fans of mathematics. It can be interesting to more qualified readers who want to get acquainted with the theory of algebraic numbers in its classical aspect.
