Welcome to MATH 95 - Algebra 3! $Edit section$

This book is here to support you every step of the way as you build a strong foundation in algebra and discover how it connects to the world around you. Algebra isn’t just a series of rules; it’s a tool for solving real problems, spotting patterns, and making confident decisions. You’ll find clear explanations, guided practice, and plenty of opportunities to check your understanding so you can learn with ease and grow your math skills with confidence.

Here’s how this book was designed to help you succeed:

Concept Introductions: New concepts and terminology in each section are introduced through definitions and visual demonstrations.
"Example" Problems: To help you solidify your understanding of new ideas after each class, several fully worked-out examples of applying the concepts are included, which show you not only how to find the answer, but why it works.
Practice Sets: After each section is a set of carefully sequenced problems that build in complexity and offer varied opportunities to apply new concepts. Working through these problems will help you deepen your understanding and grow your confidence.
Answer Key: All answers to practice problems are collected in the back of the book, so you can quickly confirm you’re on the right track.
Self-Check: At the end of each practice set, use the “self-check” questions to pinpoint any areas you’d like to revisit or get extra help with.

As you progress through the course, you’ll take an in-depth look at linear, quadratic, and rational relations, each with a focus on graphical properties, algebraic techniques, and real-world applications.. Along the way, you’ll sharpen your number sense, deepen your critical thinking, and build the persistence to face new challenges head-on. Remember: math is a way of seeing the world, and your entire Clackamas Community College community—including instructors, tutors, advisors, and peers—is here to help you view it with clarity.

Let’s get started on this exciting journey together!
