Key To Rays New Higher Arithmetic PDF Download

Excerpt from Key to Ray's New Higher Arithmetic IN the preparation of the following pages, the chief aim has been to serve the teacher. Accordingly, through a great part of the work we have merely indicated the operations required, and have thus saved the space which would be demanded for the full statements of analysis, useful chie y in recitation drill. The help afforded by a Key being of very little value under the fundamental rules, this work does not begin with the first exercises of the new higher arithmetic. In most cases, after a short study of an arithmetical problem, the operations themselves, as indicated properly by signs, will suggest the reasoning on which the solu tion is based. In the solutions here given this has been kept in view, especially where the text-book has pre sented a formula. To the teacher and to the class, alike, it will be advantageous to have the blackboard work written in accordance with this plan; and, on this ao count, early in the Arithmetic, the subject of Arith metical Signs has been formally presented.
