This book is primarily aimed at students of mathematics, computer science, and other related natural sciences, who do not have specialized knowledge in discrete mathematics.

The goal of the book is to familiarize readers with the structures of discrete and combinatorial mathematics that will be useful for further study in mathematics and its applications, and to help them both appreciate and assimilate the relevant methods and ideas, as well as develop their combinatorial thinking.

The prerequisites are minimal, making the book suitable for a broader range of readers (which includes some high school students) with an interest in mathematics.
