This book is part of a series on **Algebra:**

## Preface

## Unit 1: Numbers, Variables and Relationships

How can we use numbers and variables to find out unknown information?

Chapter 1: Elementary Arithmetic

Chapter 2: An Introduction to Algebra

Chapter 3: Solving Equations

Chapter 4: Inequalities

## Unit 2: An Introduction To Graphing

Math is a method of solving problems. You take information you know, and by manipulating it using mathematical principles, you can find information you don't know. Functions are the mathematical framework for solving problems. They have parameters, rules, and ways of being solved. This section will introduce you to functions and how to use them.
