This two-volume treatment in a single binding supplements standard mathematics courses. Written to remedy the common mistake of emphasizing generality and abstract principles at the expense of concreteness, it stresses formal manipulations, intuitive appeal, and ingenuity. It employs physical analogies, encourages problem formulation, and supplies problem-solving methods. 1973 and 1976 editions. Reprint of the John Wiley & Sons, New York, 1973 edition.
