Mathematical Olympiad in China: Problems and Solutions by Bin Xiong – A Definitive Resource for High School Math Competi

Introduction

For decades, China has dominated the International Mathematical Olympiad (IMO), producing some of the sharpest young mathematical minds in the world. Mathematical Olympiad in China: Problems and Solutions offers an exclusive window into the training ground of these champions. Compiled by the renowned mathematician Bin Xiong, this hardcover volume presents the actual contest problems and their elegant solutions from China’s most prestigious national competitions between 2010 and 2014. Whether you are a student aiming for the IMO, a teacher coaching a team, or a math enthusiast hungry for challenging problems, this book is your passport to the rigorous and creative world of Chinese mathematical olympiads.

Book Overview

This book is a comprehensive collection of problems and solutions from five major Chinese mathematical competitions: the China Mathematical Competition, the China Mathematical Olympiad, the China Girls’ Mathematical Olympiad, the Chinese Mathematical Olympiad for Primary Schools, and the Chinese Mathematical Olympiad for Junior High Schools. Each problem is presented with a clear, step-by-step solution, many of which were contributed by members of China’s national training team and IMO gold medalists. The book covers a wide range of topics—from number theory and algebra to geometry and combinatorics—at levels that progressively challenge the reader. It is designed to bridge the gap between school mathematics and the advanced thinking required for olympiad success.

Key Highlights

• Authentic Problems: Features real exam questions from China’s top mathematical competitions (2010–2014), giving readers direct exposure to the style and difficulty of elite contests.
• Expert Solutions: Solutions are crafted by national team members and IMO medalists, offering insights into the elegant, often surprising, approaches that lead to success.
• Broad Coverage: Includes competitions for different age groups—primary, junior high, and senior high—making it suitable for a wide range of students.
• Progressive Difficulty: Problems are arranged by contest and year, allowing readers to gradually build their skills from intermediate to advanced levels.
• Cultural Insight: Offers a rare glimpse into the mathematical training ecosystem that has produced the world’s top IMO teams.

Inside the Book

The book is structured chronologically, with each chapter dedicated to a specific competition and year. For example, you will find the 2010 China Mathematical Competition problems followed by their complete solutions, then the 2011 edition, and so on. The solutions are not merely answers; they are detailed expositions that explain the reasoning behind each step. Many solutions include alternative methods, commentary on common pitfalls, and references to related theorems. The book also features occasional notes from the authors that highlight the deeper mathematical ideas underlying seemingly simple problems.

Key Topics

• Number Theory: Divisibility, Diophantine equations, modular arithmetic, and prime numbers.
• Algebra: Polynomials, inequalities, functional equations, and sequences.
• Geometry: Euclidean geometry, transformations, concurrency, and collinearity.
• Combinatorics: Counting principles, graph theory, pigeonhole principle, and combinatorial design.
• Problem-Solving Strategies: Induction, contradiction, invariant method, and extremal principle.

Reader Benefits

• Sharpens Analytical Thinking: Each problem demands logical reasoning and creative insight, training your brain to approach challenges methodically.
• Builds Exam Confidence: Practicing with authentic olympiad problems prepares you for the pressure and complexity of real competitions.
• Provides Role Models: Seeing solutions from IMO gold medalists inspires you to aim higher and learn from the best.
• Supports Self-Study: The detailed solutions make it possible to learn independently, without a teacher’s guidance.
• Enhances School Performance: The advanced concepts and problem-solving techniques directly improve your grasp of school mathematics.

Learning Outcomes

By working through this book, readers will be able to solve non-routine problems that go beyond textbook exercises, develop a deeper understanding of mathematical structures, and acquire the discipline needed for high-level competition success. Students will learn to identify patterns, construct rigorous proofs, and apply multiple mathematical tools to a single problem. Teachers will gain a rich repository of challenging problems and elegant solutions to use in coaching sessions.
