WENTWORTH'S
COLLEGE ALGEBRA
REVISED EDITION
12mo. Half morocco. 530 pages. List price, $1.50; mailing price, $1.65
This book is a thorough revision of the author's "College Algebra." Some chapters of the old edition have been wholly rewritten, and the other chapters have been rewritten in part and greatly improved. The order of topics has been changed to a certain extent; the plan is to have each chapter as complete in itself as possible, so that the teacher may vary the order of succession at his discretion.
As the name implies, the work is intended for colleges and scientific schools. The first part is simply a review of the principles of algebra preceding Quadratic Equations, with just enough examples to illustrate and enforce these principles. By this brief treatment of the first chapters sufficient space is allowed, without making the book cumbersome, for a full discussion of Quadratic Equations, The Binomial Theorem, Choice Chance, Series, Determinants, and the General Properties of Equations.
Every effort has been made to present in the clearest light each subject discussed, and to give in matter and methods the best training in algebraic analysis at present attainable.

ALGEBRA FOR BEGINNERS
By DAVID EUGENE SMITH,
Professor of Mathematics in Teachers College, Columbia University
12mo, cloth, 154 pages, 50 cents
This work is intended to serve as an introduction to the study of algebra, and is adapted to the needs of the seventh or eighth school year. It is arranged in harmony with the leading courses of study that include algebra in the curriculum of the grades.
The relation of algebra to arithmetic is emphasized, the subject is treated topically, and each important point is touched at least twice. The book begins by showing the uses of algebra, employing such practical applications as are within the pupil's range of knowledge. When an interest has thus been awakened in the subject, the fundamental operations are presented with the simple explanations necessary to make the student independent of dogmatic rules. Throughout the book abundant oral and written drill exercises are provided. The work includes linear equations with two unknown quantities, and easy quadratics.
The leading features may be summarized as follows: (1) an arrangement in harmony with existing courses of study; (2) a presentation designed to awaken the interest of the pupils; (3) a topical arrangement for each half year, every important topic being repeated; (4) simplicity of explanations; (5) development of the relation of algebra to arithmetic both in theory and in applications; (6) emphasis laid on the importance of oral as well as written algebra.
