The "Algebra For Tutoring, Book #1, Basics of Algebra" book was written following the concept of few words and many formulas and exercises.
We hope this book will be useful for tutors, those being tutored, specialists, college, and school students and teachers, as well as others who wish to improve or enforce their, or their students', knowledge in general mathematics and in the Basics of Algebra particularly.
The book may also be useful to those who wish to study mathematics on their own.
