This book is a carefully curated collection of 30 beautiful inequality problems drawn from olympiad mathematics.Each problem was selected not only for its difficulty, but primarily for its elegance, depth, and the clarity of ideas it reveals. The collection is designed to serve as both a trusted companion and a source of inspiration for students preparing for advanced mathematical competitions, including high-level international olympiads.At the same time, it remains accessible to motivated beginners, featuring simpler yet genuinely beautiful problems that help develop intuition and mathematical taste. The problems span a wide range of difficulty levels: from introductory inequalities that highlight fundamental ideas, to challenging and sophisticated problems intended for experienced olympiad contestants.This balance reflects the belief that mathematical beauty is not defined by complexity alone, but by insight, structure, and elegance of solution. This collection is the result of a personal mathematical journey shaped by curiosity, persistence, and a deep appreciation for inequalities.It is dedicated to students who seek not only to solve problems, but to understand them — and to discover beauty within mathematics.
