### From the Preface:

"The goal of this course is to develop your ability to read, write, think, and do mathematics and to give you command of the facts and methods of algebra and trigonometry. It emphasizes everything you need to understand to be prepared for calculus.

"A unique feature of this course is its emphasis on developing fluency in the abstract and symbolic language of algebra. That "foreign" language is extremely important because it is the most effective and efficient language in which to learn, understand, recall, and think mathematical thoughts."

From the Preface: "A unique feature of this course is its emphasis on developing fluency in the abstract and symbolic language of algebra. That "foreign" language is extremely important because it is the most effective and efficient language in which to learn, understand, recall, and think mathematical thoughts."
