An Elementary Introduction to Degree Theory . Definition and main properties of authorship B. In. Ivanova is a fascinating and deep dive into the world of mathematical theory, which, despite its apparent simplicity, opens up many opportunities for the reader to understand more complex concepts. This publication will become an indispensable assistant for students, teachers and anyone interested in mathematics and its applications in various fields of science. The book focuses on degree theory, one of the cornerstones of algebra, which plays a key role in understanding not only mathematical operations, but also more complex concepts such as functions, equations, and their graphs. In. In. Ivanov, known for his clear and accessible explanations, offers the reader not just a set of formulas and definitions, but also a deep understanding of how and why certain mathematical constructions work. The book begins with the basics - determining the degree and its properties, and then smoothly moves on to more complex topics, such as the rules for working with degrees, their application in equations and inequalities. This book will be interesting not only for students studying mathematics at the elementary level, but also for teachers who are looking for a way to explain complex concepts to their students. It will also find many useful for themselves and lovers of mathematics, seeking to deepen their knowledge and understand how theoretical aspects can be applied in practice. If you are interested in topics such as algebra, mathematical analysis or even physics, then this publication will be a real find for you. One of the key topics raised in the book is the relationship of degree theory to other areas of mathematics. In. In. Ivanov masterfully shows how concepts that may seem isolated are actually intertwined and form a single picture. This makes the book not only a textbook, but also a real guide to mathematical thinking. The reader will be able to see how the degree is used in a variety of contexts, from simple arithmetic problems to complex mathematical models. The author's style is clear and logical, which makes the reading process fascinating and not tedious. In. In. Ivanov has extensive experience in teaching and writing educational materials, which allows him to explain even the most complex topics in a simple and accessible language. His other well-known works, such as Basics of Algebra and Mathematical Analysis for Beginners, have also earned recognition for their clarity and structure. The book "Elementary Introduction to Degree Theory" is not just a textbook, but a real find for anyone who wants to understand and master mathematics. It will be useful both for students preparing for exams, and for university students seeking to strengthen their knowledge. In addition, it will be an excellent resource for teachers who are looking for new approaches to explaining complex topics. If you are looking for a book that will help you understand degree theory and learn how to put it into practice, then "Elementary Introduction to Degree Theory. Definition and main properties" B. In. Ivanova is exactly what you need. Do not miss the opportunity to discover the world of mathematics from a new perspective!
