Présentation de l'éditeur
It is believed that there is a unity of plan and execution in theE lementary and the Completer Arithmetic of this course which is found in no other arithmetical series. As the processes of oral and written arithmetic are precisely the same, the so-called Mental Arithmetic should not be made a distinct study. In fact, without ignoring other indispensable studies, there is no time for two daily lessons in arithmetic. The Progressive Oral and Written Drills, and the Inductive andO ralE xercises, provide so abundantly for developing and fixing all the introductory and fundamental facts, that a separate book would be superfluous. In the Progressive Oral and Written Drills, advancement is made from the simpler to the more difficult combinations. The pupil almost unconsciously learns and retains the various facts or combinations, and recalls them without apparent thought. Such facility as this in addition, subtraction, multiplication and division, can be acquired only by the graded work of advancing from one digit to another. The definitions, rales, analyses and manner of treatment, are the same in both books. The fundamental rules are developed separately and are afterward combined. It is believed that by treating them conjointly at the start, the child is brought too abruptly to the consideration of a union of principles, which, for the sake of simplicity and directness, should be treated apart. Mental growth and strength depend upon clear conceptions, and rest upon the fundamental principle, Do one thing at a time and do it well. Hence, after treating addition and subtraction separately, they are combined, the same course being followed with multiplication and division ;also with fractions. In theS tandard A rithmetics, the work, which is partly oral and partly written, has been prepared with great care, and will be found fresh, vigorous, and practical. The aim

Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
