The book consists of six parts: mathematical logic, set theory, graph theory, preliminary combinatorial analysis, algebraic structure, preliminary formal language and automata. Each part includes three aspects: content summary, exercises matching this part, and answers to exercises. Each question has a detailed answer and analysis, and some questions give different solutions or easy mistakes and point out the reasons.
The Solution of Discrete Mathematics (Fifth Edition) can be used as an auxiliary textbook of Discrete Mathematics (Fifth Edition) and also as a reference book for other discrete mathematics textbooks.
