From the reviews:
"This book uses the medium of problems to enable us, the readers, to educate ourselves in matters polynomial. In each section we are led, after a brief introduction, into a sequence of problems on a certain topic. If we do these successfully, we find that we have mastered the basics of the topic ... I approached this book with some prejudice against its non-textbook approach; but it won me over entirely. It is not easy to write a book that will interest both the bright high-school student and the practicing mathematician. That it does so is a tribute to the author's scholarship, style, choice of material, and careful attention to detail." -Mathematical Reviews
