The Book of Mathematics . Discrete mathematics” performed by the team of authors is not just a textbook, but a real find for everyone who seeks to understand the world of numbers and logical structures more deeply. This publication will become an indispensable assistant for students, graduate students, teachers and anyone interested in mathematics, computer science and related disciplines. Discrete mathematics is a field that covers a variety of topics, from combinatorics and graph theory to algorithms and computational theory. The book carefully elaborates the basic concepts and methods that allow the reader not only to learn the theory, but also to apply it in practice. Each section is filled with examples, tasks and illustrations, which makes the learning process more exciting and accessible. Who is this book intended for? It will be of interest not only to students of technical specialties, but also to everyone who wants to develop logical thinking and learn how to solve complex problems . If you study at the Faculty of Mathematics, Computer Science or Engineering, then this publication will become your faithful companion in the world of numbers and algorithms. Even if you just love solving puzzles and want to expand your knowledge, "Mathematics. Discrete mathematics will open up new horizons for you One of the key themes of the book is combinatorics - the science of combinations and permutations. Readers will be able to learn how to count the number of ways in which objects can be organized, and how this knowledge is applied in real life, for example, in cryptography or probability theory. The authors also pay attention to graph theory, which finds application in a variety of fields, from computer networks to social research. An equally important topic is algorithmization - the process of creating algorithms for solving problems. The book presents various algorithmic approaches and methods that will help readers not only understand the theory, but also learn how to apply this knowledge in practice. This is especially true for those who are planning a career in programming or software development. The style of the authors is distinguished by clarity and accessibility, which makes it easy to assimilate complex concepts. They use many real-life examples to demonstrate how discrete mathematics can be applied in various fields. This makes the book not only a tutorial, but also an interesting read for those who want to expand their horizons. If you are looking for similar works, pay attention to books on graph theory, combinatorics and algorithms, such as Corman's Algorithms: Construction and Analysis or Richard Stinbeck's Combinatorial Methods. These books can also complement your understanding of discrete mathematics and its applications. Finally, “Mathematics . Discrete Mathematics is not just a book, but a whole world that opens before you with every page. It offers readers a unique opportunity to immerse themselves in the fascinating world of numbers and logic, developing skills that will be useful not only in their studies, but also in their lives. Don’t miss the chance to be a part of this mathematical adventure!
