Extension, Iowa State College TOTAL ISSUE, FOURTEEN THOUSAND NEW YORK JOHN WILEY & SONS, INC. LONDON: CHAPMAN & HALL, LIMITED QA103 13 Copyright, 1915 BY R. BURDETTE DALE Printed in U. S. A. PRESS OF 3/26 PREFACE This book was written for the purpose of presenting the subject of arithmetic, as used in the daily work of the carpenter and builder, in a simple form. It is intended for the practical man as well as for the beginner and the student. The material is such that the work can be followed successfully by those who have had an eighth-grade education. Upon the completion of this study the student should be prepared to take up the problem of estimating the cost of buildings. The author has not attempted to treat the subject exhaustively. Though the first chapters may seem elementary to some, they will furnish a much-needed review to others. Geometry is touched upon merely to serve as a foundation for the work in mensuration. Practical applications of geometric truths are emphasized, while rigid proofs and developments are omitted. Two chapters on the steel square, that most useful tool of the carpenter, are included. Many of the problems do not admit of exact answers for the reason that the judgment of the student plays an important part in the solution. Different results will be obtained, depending upon the lengths and widths of the boards chosen and other similar details. Careful planning for the economical use of material is required, for this is an essential training for the work of the practical carpenter. |
