Written at a high school - college introductory level, it is more than just a superb textbook. Covers number sequences, functions and their graphs, large numbers and logarithms, symmetry and regular figures, mathematical curves, methods of counting, probability, an introduction to statistics, and topology. Answers for selected exercises are provided in the back of the book. The Manual is not needed to learn math with this book. Technical terms don't exist in dreams.
Nobody dreams in big words.
So when the number devil talks in images and sets numbers hopping instead of raising them power of x or y, it's not just kid stuff. In dreams we do as we please. By talking about all the big ideas and unsolved problems he manages to give the reader a grounding and appreciation for the basic skills of math. The number devil frequently dramatizes his presentations, and the illustrations are humorous and often very helpful. Covers all ages.
