Professor DeWitt’s book is set up to make sense to students. In each chapter, they are first introduced to a real life application of the topic they are about to learn. As each topic is taught, students are presented with graph images, examples, and easy to follow proofs. Each chapter is divided into subchapters, each with their own set of problems for students to test their knowledge as they learn. Finally, at the end of each chapter is a series of exercises that combine all topics learned in that section of the book.
