"Remote Mathematical Olympiads" is a unique publication that will become a real find for everyone who is interested in mathematics and seeks to develop their analytical abilities. Authors, among whom H. is distinguished B. Vasiliev, collected in this book not only fascinating tasks, but also methodological recommendations that will help the reader to prepare for participation in mathematical olympiads, both correspondence and full-time. The book covers a wide range of topics, ranging from elementary arithmetic to more complex concepts such as combinatorics, number theory, and geometry. Each chapter contains carefully selected tasks that will help the reader not only to test their knowledge, but also to deepen them. It is important to note that the challenges vary in difficulty, making the book available to both beginners and more experienced participants in the Olympics. If you are a student who is preparing for the Olympics, or a student who wants to improve their skills in mathematics, this book will become your reliable assistant. It will also be of interest to teachers who are looking for new approaches to teaching their students and want to diversify the learning process.

Topics raised in the "Mathematical Olympiads in absentia" go beyond simple problem solving. The authors emphasize the importance of logical thinking, creativity and the ability to work with information. Each problem becomes not just a mathematical exercise, but a real challenge that requires a non-standard approach. This makes the book especially valuable for those who want to learn how to think critically and find solutions in difficult situations. Author's style, N. B. Vassilyeva, distinguished by clarity and accessibility. He is able to explain complex concepts in simple language, which makes the material understandable even for those who are not professionals in the field of mathematics. In this edition, Vasilyev uses his rich experience of teaching and participating in the Olympiads, which gives the book special value. In addition, his other works, such as Mathematics for Olympiads and Tasks for Exam Preparation, also deserve attention and can complement the study offered in the Correspondence Mathematical Olympiads. This book will not only help you prepare for the Olympics, but will also be a source of inspiration for further study of mathematics. It encourages the reader not to be afraid of difficult tasks, but, on the contrary, to perceive them as an opportunity for growth and development. You will be able to see how mathematics permeates many aspects of our lives, and perhaps discover new horizons in this fascinating science. If you are looking for literature that will help you to improve your mathematical skills, develop logical thinking and prepare for the Olympiads, the “Remote Mathematical Olympiads” are exactly what you need. Do not miss the chance to immerse yourself in the world of fascinating mathematics and discover new horizons of knowledge!
