This book is an auxiliary textbook with the textbook Introduction to Discrete Mathematics published by Science Press in 2002. The content is arranged in the order of the corresponding chapters in the textbook, and each chapter includes two parts: content overview and problem solving. The former focuses on the most basic concepts and theorems of discrete mathematics, while the latter is a detailed reference solution to the problems in the textbook. The purpose of this book is to develop ideas, provide readers with methods and skills to solve problems, deepen readers' understanding of discrete mathematics application and its connection with computer science, and gradually enhance their ability to analyze and solve problems.

This book can be used as a teaching reference book for discrete mathematics courses for undergraduates and junior college students majoring in computer and related majors in colleges and universities, as well as as a learning book for computer software and hardware research and development personnel and application personnel, and as a review book for college graduates to take part in postgraduate entrance examination.
