Algebra

Welcome to the Wikibook of

Preface
Algebra is the branch of mathematics concerning the study of the rules of operations and relations, and the constructions and concepts arising from them, including terms, polynomials, equations and algebraic structures.

You've been asked to buy peanuts for you and your friends at a football game. You've collected $12.50. One bag is $2.75. You want to know how many bags you can buy. This is an algebra problem! Related problems are how much money will be left over, and what should you buy or in what proportions should you return the extra money to your friends.

Algebra helps us to predict things that we don't yet know and to determine the relationships between the things we do. Algebra is a powerful and rich branch of mathematics that is useful in everyday life as well as business, engineering, and other technical fields.

Preface
Chapter 0: An Introduction to Mathematics 

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.

Chapter 5: The Cartesian Plane Chapter 6: Graphing Linear Functions Chapter 7: Systems and Matrices Chapter 8: Piecewise Functions 

Unit 3: Polynomials
Chapter 9: Quadratic Functions Chapter 10: Higher-Degree Polynomials 

Unit 4: Other Functions
Chapter 11: Properties of Functions Chapter 12: Exponents and Logarithms Chapter 13: Rational and Radical Functions Chapter 14: Trigonometry 

Unit 5: Algebra in Discrete Mathematics
Chapter 15: Sequences and Series Chapter 16: Probability and Statistics 

Unit 6: Analytic Geometry
Chapter 17: Conic Sections Chapter 18: Parametric Equations and Polar Coordinates Chapter 19: Vectors 

Unit 7: Advanced Algebra
Now that you have completed your mathematical journey, you may be wondering where to head over next. This unit provides six optional chapters that can be done in any order you please. The six chapters are meant to be independent from one another, and any of the chapters can be skipped entirely to put more focus on the topics that are of greater interest to you.
