W elcome to your new pre-calculus book! Let us try to explain why we believe youve made the right choice. This probably isnt your first rodeo with either a textbook or other kind of guide to a school subject. Youve probably had your fill of books asking you to memorize lots of terms (such is school). This book isnt going to do thatalthough youre welcome to memorize anything you take an interest in. You may also have found that a lot of books jump the gun and make a lot of promises about all the things youll be able to accomplish by the time you reach the end of a given chapter. In the process, those books can make you feel as though you missed out on the building blocks that you actually need to master those goals.

With Must Know High School Pre-Calculus, weve taken a different approach. When you start a new chapter, right off the bat you will immediately see one or more must know ideas. These are the essential concepts behind what you are going to study, and they will form the foundation of what you will learn throughout the chapter. With these must know ideas, you will have what you need to hold it together as you study, and they will be your guide as you make your way through each chapter.

To build on this foundation, you will find easy-to-follow discussions of the topic at hand, accompanied by comprehensive examples that show you how to apply what youre learning to solving typical pre-calculus questions. Each chapter ends with review questionsmore than 250 throughout the bookdesigned to instill confidence as you practice your new skills.

This book has other features that will help you on this pre-calculus journey of yours. It has a number of sidebars that will both help provide helpful information and serve as a quick break from your studies. The sidebars (by the way) point out important information, as well as tell you what to be careful about pre-calculus-wise. Every once in a while, an sidebar (in real life) will tell you what youre studying has to do with the real world; other IRLs may just be interesting factoids.

In addition, this book is accompanied by a flashcard app that will give you the ability to test yourself at any time. The app includes more than 100 flashcards with a review question on one side and the answer on the other. You can either work through the flashcards by themselves or use them alongside the book. To find out where to get the app and how to use it, go to the next section, The Flashcard App.

We also wanted to introduce you to your guide throughout this book. Chris Monahan has more than 30 years experience teaching math at the high school and college levels. He knows what you should get out of a pre-calculus course, and his strategies will help get you there. Chris has seen the typical kinds of problems that students can have with pre-calculus, and he is experienced at solving those difficulties. In this book, he uses that experience to show you not only the most effective way to learn a given concept but how to get yourself out of traps you might have fallen into. Weve had the pleasure of working with Chris before and are confident that were leaving you in good hands.

Before we leave you to Chriss surefooted guidance, let us give you one piece of advice. While we know that saying something is the worst is a clich, if anything is the worst in pre-calculus, its getting used to functions. Let Chris introduce you to the concept and show you how to apply it confidently to your pre-calculus work. Take our word for it, mastering functions will leave you in good stead for the rest of your math career.

Good luck with your studies!
