Book Description
Excerpt from Mechanical Arithmetic: Or the History of the Counting Machine This lecture by the well-known inventor and manufacturer of the famous calculating machine known to all 'american bookkeepers and office men -as the Comptometer, will be appreciated by all business men and students of Business who realize the wonderful strides made in the last quarter of a century in the mechanical aids to efficiency in the accounting departments of commercial life. Mr. D. E. Felt stands high on the roll of successful Amer ican inventors, and, unlike so many of them, he possesses a well-developed business instinct that has enabled him to reap the due reward of his inventive genius. His standing as an inventor is recognized in Europe as well as in the United States, and during the visits to the European museums to which he refers in his lecture he was signally honored by being permitted to make close examination and tests of the historic calculating machines preserved in those institutions; so that he speaks with unusual authority on this interesting subject of the development of Mechanical Arithmetic from the earliest times of which records exist.

Book Description
Excerpt from Modern Commercial Arithmetic A course in business arithmetic should train the pupil to figure correctly, easily, and rapidly, and should fit him to solve the problems that arise in the ordinary course of business. To this end Modern Commercial Arithmetic gives a brief review of the fundamental operations, fractions and decimals, introducing short practical methods. The mechanical part of arithmetic is illustrated and explained by diagrams, examples, operations, and notes. The intellectual part is developed in the pupil's mind by mental problems, questions, and statements. A student should solve a problem from his knowledge of the facts or conditions of the problem and the principles involved; therefore, rules and cases are superseded by development exercises which will make him thoughtful and independent. In the business office problems do not come tabbed with article and rule, but the business man must first discover the principle that is involved and then by a process of reasoning determine the result. It has been the object of this work to present the problems as nearly as possible as they are presented in the business office. When the pupil changes from the school to the office he will find the change in the method of thought involved as slight as possible. The student in school has no time to waste and therefore this work contains no puzzles or catch problems. Subjects that do not arise in ordinary business transactions are omitted. The author's aim has been to present a work that would give the pupil such instruction as he needs, and to set it forth in the manner he will meet it in the business office. It is hoped and believed that an inspection and trial of the work will show that he has succeeded. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Will's Commercial Arithmetic, Presenting the Best Usage in Modern Business Practice It has been found extremely difficult, if not impossible, for the average student of arithmetic to remember its many topical rules and explanations, and to exercise due discrimination in giving to each its local application. "Will's Commercial Arithmetic" has therefore ignored this unsatisfactory method of treatment, and has substituted the few cardinal principles which underlie all arithmetical processes, and which can be used in the solution and explanation of all problems. The learner is thus liberated from slavish adherence to mechanical rules and hackneyed explanations which are soon forgotten, and is properly cultured in the exercise of his reasoning faculties in the solution of problems, the effect of which is permanent. The only conceivable modifications of any given number in a problem are effected either by increasing it or by decreasing it. The law of increase or decrease is uniform in its application. Addition and multiplication are the only known numerical processes for increasing a number, the former being employed when the increase is by one or more given unequal components, and the latter when by equal components. Conversely, subtraction and division are the only known means for diminishing a number, the former being employed when the decrease is by one or more given unequal components, and the latter when by equal components. Each of the four preceding processes is thus seen to be invariably limited to its own prerequisite conditions; and the proper process to select will depend upon the particular prerequisite conditions which are given. The intelligent solution of a problem can therefore involve nothing further than the identification of its numerical terms, a knowledge of the specific process to which these identified terms invariably belong, and the mechanical performance of that process.
