This is not just a textbook, but a real encyclopedia, which harmoniously combines deep mathematical ideas and accessible presentation. The authors, known for their outstanding achievements in the field of mathematics, offer the reader to plunge into one of the most ancient and mysterious branches of science - number theory. From the first pages of the book, the reader finds himself on an exciting journey through numerical worlds, where prime and composite numbers, divisibility and residues, prime numbers and their distribution become the main characters. The authors masterfully guide the reader through complex concepts, explaining them with intuitive examples and illustrative illustrations. This makes the book available to both students and those who are simply interested in mathematics, but do not have in-depth knowledge in this field. The book will be of particular interest to students of mathematical faculties, students passionate about mathematics, as well as anyone who wants to expand their knowledge of numbers. It is suitable for both beginners and more experienced readers who want to deepen their knowledge in number theory. If you’ve ever wondered why prime numbers are so important, or want to understand how numbers interact with each other, this book will be a real discovery for you. The topics raised in Number Theory cover a wide range of issues, from prime numbers and their properties to more complex concepts such as Fermat's Theorem and the Riemann Hypothesis. The authors not only outline the theoretical aspects, but also offer a variety of tasks and exercises that help to consolidate the knowledge gained. This makes the book not only a theoretical tool, but also a practical tool for studying mathematics. The style of Borevich and Shafarevich is distinguished by clarity and logic. They are able to explain complex things in simple language, which makes their work especially valuable for a wide audience. Both authors are recognized experts in their field, and their works, such as Algebra and Geometry, are also highly respected and popular. Their experience and in-depth knowledge allow them to create materials that not only teach, but also inspire.
