Solutions to Discrete Mathematics (5th Edition) is a complete solution to the book Discrete Mathematics (5th Edition) (edited by Geng Suyun, Qu Wanling and Sean, published by Tsinghua University Publishing House).

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 matched with this part, and exercises solutions. Each question has a detailed answer and analysis, and some questions give different answers or point out the reasons for the mistakes.
