Nearly all fractional calculations are entir…ely avoided, and involved principles and rules have been simplified and made easy of comprehension.

This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
