THE ELEMENTS OF WRITTEN ARITHMETIC; COMBINING ANALYSIS AND SYNTHESIS; ADAPTED TO THE BEST MODE OF INSTRUCTION FOR BEGINNERS. BY JAMES S. EATON, M. A., INSTRUCTOR IN PHILLIPS ACADEMY, ANDOVER, AND AUTHOR OF A SERIES An the Clerk's Office of the District Court of the District of Massachusetts. ROCKWELL & CHURCHILL, Printers, Boston. PREFACE. DURING the few years EATON'S SERIES of ARITHMETICS has been before the Educational Public, it has been demonstrated, by their cordial reception—by their circulation, already extensive and rapidly increasing that a deep-felt want for books of their high character has been satisfactorily met. In the vast field at the South now being opened to educational advantages in the extensive and rapidly growing settlements of the West, and in the cities and manufacturing districts of the older States, there is a large class of pupils whose school days are very limited. To these next to reading and writing a brief, practical course of Arithmetic must always form the most useful part of school training. It was to meet the wants of this class that the present work was projected by its author. Owing to an unforeseen event, its completion has devolved upon others. This has been the occasion of some delay in its publication, which however has been taken advantage of to make it as perfect as possible. This little work then is a short, practical course of Written Arithmetic, embracing the topics actually necessary to be mastered to enable one to pursue with intelligence the ordinary business avocations of life. Special attention has been bestowed upon the FUNDAMENTAL RULES, UNITED STATES MONEY AND PERCENTAGE, and a simple but full exposition of the NEW METRIC SYSTEM is also presented. |
