“Collection of problems of mathematical olympiads” by Rozhkov, Kurdevanidze and Panfilov is not just a book, but a real find for everyone who seeks to deepen their knowledge in mathematics and prepare for olympiads of various levels. This collection is a carefully selected set of tasks that covers a wide range of topics and levels of complexity, from basic concepts to more advanced and non-standard tasks that will make even the most experienced mathematicians think. The book is intended for schoolchildren, students and all lovers of mathematics who want to test their strength and develop logical thinking. It will be especially useful for those who are preparing for mathematical Olympiads, competitions and exams, where not only knowledge of the theory is required, but also the ability to apply it in practice. If you are in high school or in your freshman year of university, or just want to improve your problem-solving skills, this collection will become your trusted assistant. The authors of the book are experienced teachers and mathematicians who know how important it is not only to solve problems, but also to understand their essence. They offer readers not just ready-made solutions, but detailed explanations and methods that will help develop analytical thinking and learn to approach tasks from different angles. In this collection you will find tasks that require creativity, logic and intuition, making it an ideal tool for preparing for the Olympics. The topics raised in the collection are diverse and cover areas such as combinatorics, number theory, geometry, and algebra. Each task is accompanied by comments and tips, which allows the reader not only to find the right answers, but also to understand how to come to them. This makes the book not only a training tool, but also a real learning material that can be used in the learning process. The style of the authors is distinguished by clarity and accessibility, which makes the material understandable even for those who are just starting their way in the world of mathematics. Their approach to learning is based on the principle of “from simple to complex”, which allows you to gradually increase the level of complexity of tasks and self-confidence. In addition, in the collection you can find the tasks that were proposed at the real Olympics, which adds an element of practice and helps the reader to prepare for real tests. If you are looking for books similar in genre, pay attention to "Mathematical Olympiads for schoolchildren" or "Mathematical problems for preparing for the exam" . These books will also help you develop math skills and prepare for exams. In conclusion, the “Compendium of Problems of Mathematical Olympiads” is not just a book, but a whole world of mathematical discoveries that awaits you. It will become your faithful companion in a fascinating journey through the world of numbers and formulas, help develop critical thinking and teach you how to find solutions in the most difficult situations.
