PREFACE

is given

THE STANDARD ARITHMETIC is the second book of a series, yet is complete in itself and in many schools may be used throughout all the grades, if such use be preceded by a little preparatory work in number.

Attention is asked to the order of presentation, to the great number of practical problems, and to the applications of arithmetical processes to actual conditions arising in business and in all conditions of life. The teacher will find an unusual number and variety of problems and will note the sufficiency and value of the summaries. Some

space to those simpler algebraic processes and geometric constructions which are now being tried out in the higher grades of elementary schools, and the introduction to certain phenomena of familiar science which are susceptible of mathematical solution or definition will appeal to the interest of many students. Sufficient space is given to Mensuration and to the Metric System.

Unnecessary or obsolete processes, tables, or facts have been eliminated.

The book is presented to progressive and earnest teachers in the belief that it will give to them abundant material for the work of the several four or five higher years of the elementary school course and that it will appeal, in the nature or material of the exercises offered, and from which selection may be made, to the interests of their pupils.

New York, July, 1910.
