This book has been written to meet the demand for a practical course in applied mathematics which shall coördinate the schoolroom lesson and the actual problem of the industrial and commercial world. It presents the body of mathematical information which is likely to be of daily service, no matter what one's occupation may be.
Applied Mathematics is the outgrowth of twelve years of experimentation in a high school of over two thousand students, and the exercises in the book have stood the test of classroom trial. The examples and problems have been selected from many fields — industrial, commercial, mechanical, agricultural—and, as far as possible, are such as occur in the household, on the farm, in the factory, and at the office. The book gives in teachable form:
(1) An adequate treatment of the fundamental operations of arithmetic, with proper attention to modern methods of performing these operations.
(2) A consideration of ordinary business transactions.
(3) A sufficient acquaintance with the symbols of algebra and of algebraic operations to enable the student to interpret and apply simple formulas.
(4) Enough geometry to enable him to compute the areas and volumes of the common geometric figures.
(5) A study of graphic charts and their use.
(7) Practice in the power to judge a computed result with reference to its reasonableness.
Having drawn on various sources for materials, the author takes this opportunity to express his indebtedness to numerous interested teachers and technical workers whose criticisms and advice have been of invaluable service in the preparation of the book. Especially does he desire to acknowledge obligation to his friend Dr. Nathaniel L. Gardner, of, the University of California, for kindly assistance and sympathetic encouragement.
