PREFACE.

ROBINSON'S Rudiments of Arithmetic, in its various editions, has probably had a greater sale than any arithmetic of its grade ever published. Although this edition is a thorough revision, all the features which have contributed to the popularity of the Rudiments have been retained, and the changes made have been only such as would bring the book up to date and make it even more valuable to teachers and pupils.

One very valuable feature of the revision consists in the addition of about forty pages of Introductory Exercises. These adapt the book for use in a two-book series, in connection with the Practical Arithmetic. They are of a general character, and are designed especially as suggestions. In the hands of an experienced teacher, they may be greatly extended, and will afford invaluable exercise upon the elementary principles of arithmetic.

On the other hand, if preferred, the book may be used as the second of a three-book series, in which case the Introductory Exercises may be omitted.
