Title: The science of numbers simplified
Description: A Book of Practical Short Rules in Mathematics for Business Men, Farmers, Mechanics, and Accountants.

From the Preface: 

This little book is designed for those who are not expert with figures.

The different rules are set forth in a manner that any one who has acquired a knowledge of the fundamental principles of mathematics can readily understand them. They are simple and accurate. [Note: In addition to explaining various principles of mathematics, the author also presents a number of nifty tricks for doing complex arithmetic quickly and easily.]

This book is designed as a self-instructor for home study. Its arrangement will also make it valuable for use in schools and business colleges, as an auxiliary to the ordinary school arithmetics. Its chronological department is a special feature. 

If the reader runs through this work at a glance, it will probably do him no good, but if he takes a pencip and paper and practices a few examples of the different rules explained, he will doubtless acquire some valuable information about this important science.
