When introducing mathematical ideas, this book moves from the concrete to the abstract, rather than the reverse. It is the authors philosophy that learning is increased when students can relate a concept to something in their lives. This approach increases both interest and motivation. Students see the importance of a topic from a practical and intuitive point of view, with models and applications playing a central part in the learning process.
