An introduction to insights and concepts of algebra that are significant for computer science. Presented in the form of self-contained lessons, the mathematical terms are gradually developed and motivated as much as possible through practical problem scenarios. In addition to the mathematical foundations, studying this book enhances abstraction skills and problem-solving abilities, which are essential competencies for computer scientists. With its excellent didactic structure, along with numerous examples and exercises featuring many hints for solutions, the book is well-suited both as a companion to relevant courses and for self-study as well as exam preparation. The author has made some rearrangements and added further cross-references, making the content structure more logical. Furthermore.
