This text bridges the gap between traditional and reform approaches to algebra encouraging students to see mathematics in context. It presents fewer topics in greater depth, prioritizing data analysis as a foundation for mathematical modeling, and emphasizing the verbal, numerical, graphical and symbolic representations of mathematical concepts as well as connecting mathematics to real life situations drawn from the students' majors.
- The problems, the models and the real life data are the three features of this book. They are used to relate the mathematics to the students' lives and to show the usefulness and relevance of the mathematics to the modern reality.

“I’m excited. I want to do all of the explorations now. When can I get my copy to teach with?”
“It’s a college algebra text that is built on real life examples and concepts. Students learn through using real data, hands on activities, and sections that slowly guide them to extensions of the previous concept. The explorations are wonderful.”
“[This book] gets the students to think beyond the manipulations and see that the mathematics they are learning really does have a purpose.”
“…These are exactly the type of examples that I look for when I review college algebra books for adoption! The applications included are also similar to problems discussed in prominent research articles in mathematics education…”
“Very promising. I like how the exercises are categorized (Fundamentals, Think About It, Skills, Contexts). I also like how material is not used and then forgotten but is used in upcoming sections…”
“It seems a great book; maintaining a good balance of skills-based exercises and explorations-based exercises. I also like the tone of the textbook (story telling) and the connection to real-life applications.”
