This textbook is easy to understand, specifically designed for beginners in mathematics. Among the many books on linear algebra that you can find in the library or a bookstore, this one is particularly well-suited as your first math book. The style is casual, fun, light, and entertaining. Efforts have been made to avoid common pitfalls, such as phrases like "as can be easily seen," "trivially follows," or "it is immediately obvious." With numerous learning aids, the book is ideal for self-study: for each chapter, there is initially a series of over 250 "very simple" questions for immediate assessment; then there is a rich selection of easily solvable exercises, and finally, in-depth "projects." In total, there are over 300 exercises, complete with tips for their solutions.
