# Book I

Welcome to teaching yourself the language of mathematics. I am excited to share with you successful methods to teach yourself this universal language.  Let us begin with BOOK I

The books are printed one sided and the blank page is for notes, to practice problems and to write mathematics.

Practice all solved examples yourself. It is the best way to test if you can recall the key concepts used in each example. Mathematics is a contact sport.

CONTENTS:

1. Brief History of Mathematics
2. Lesson on place value and absolute value using the decimal system. Use another number system to highlight why the decimal system used today is effective and efficient.
