The series is edited by the head coaches of China's IMO National Team. Each volume, catering to different grades, is contributed by the senior coaches of the IMO National Team. The Chinese edition has won the award of Top 50 Most Influential Educational Brands in China.The series is created in line with the mathematics cognition and intellectual development levels of the students in the corresponding grades. All hot mathematics topics of the competition are included in the volumes and are organized into chapters where concepts and methods are gradually introduced to equip the students with necessary knowledge until they can finally reach the competition level.In each chapter, well-designed problems including those collected from real competitions are provided so that the students can apply the skills and strategies they have learned to solve these problems. Detailed solutions are provided selectively. As a feature of the series, we also include some solutions generously offered by the members of Chinese national team and national training team.

In China, lots of excellent students who are good at maths take an active part in various maths contests and the best six senior high school students will be selected to form the IMO National Team to compete in the International Mathematical Olympiad. In the past ten years China's IMO Team has achieved outstanding results — they have won the first place almost every year.The author is one of the senior coaches of China's IMO National Team, whose students have won many gold medals many times in IMO.This book is part of the Mathematical Olympiad Series which discusses several aspects related to maths contests, such as algebra, number theory, combinatorics, graph theory and geometry. This book will, in an interesting problem-solving way, explain what probability theory is: its concepts, methods and meanings; particularly, two important concepts — probability and mathematical expectation (briefly expectation) — are emphasized. It consists of 65 problems, appended by 107 exercises and their answers.

This book is intended as a reference for readers learning factorization. The first eight chapters are designed at the junior high school level and are suitable for most students, while the final five chapters are slightly more advanced, providing interested readers with opportunities for further exploration.Factorization plays a key role in mathematics learning, serving as a bridge between prior knowledge and future study. Mastering it not only helps students review the four fundamental operations of integral expressions but also lays a solid foundation for the study of fractional expressions. It is also indispensable for the transformation and solution of equations.Problems in factorization are highly varied and can be solved with flexible and diverse methods. Through these, students can develop their abilities in observation, calculation, and creative thinking. Therefore, it is an important part of junior high school mathematics competitions.
