This book is structured to take readers on a journey from the fundamental building blocks of inequality theory all the way to advanced, creative problems. It begins with a comprehensive overview of key algebraic and geometric inequalities, providing the tools needed to tackle more complex challenges. The heart of the book lies in its extensive collection of original problems, organized by the number of variables and symmetry. These aren’t just random exercises—each one is designed to be both beautiful and demanding, requiring insight rather than brute force. The final chapter offers detailed solutions, often with multiple approaches and helpful commentary, making it a fantastic learning resource. The writing is passionate and personal, reflecting the author’s own journey and love for the subject.
