  In this book, there are five chapters: Systems of Linear Equations, Vector
Spaces, Homogeneous Systems, Characteristic Equation of Matrix, and Matrix Dot
Product. It has also exercises at the end of each chapter above to let students
practice additional sets of problems other than examples, and they can also
check their solutions to some of these exercises by looking at Answers to
Odd-Numbered Exercises section at the end of this book. This book is very
useful for college students who studied Calculus I, and other students who want
to review some linear algebra concepts before studying a second course in
linear algebra. This book is available online for free in google books and
