Education > Complete treatise on practical arithmetic and book-keeping

PREFACE.
In the extraction of roots, I have given a new, gen;
ral, and very expeditious method, by which the third anU
higher roots may be found, without the intolerable ki
hour attending the common methods.
*#*In this new edition, the whole of the examples am
tables have been computed anew; and corrected, wher
any errors had crept into them. And an Appendix i
added, containing many useful rules and examples
tending to illustrate the connection and dependence o
the rules upon one another, and to render the opera
tions more easy and expeditious. Interminate decimal:
are introduced, and general and easy rules are giver
for working them; by which means, many question:
may be performed, with less than half of the figure;
that would be sufficient by the rules formerly given
A nd at the end there is given a new rule for extracting
the Cube Root, and the method of measuring and cal¬
culating the works of Artificers. Likewise, many er¬
rors of the press that had escaped in former editions,
are here corrected: So that it is hoped nothing is omit¬
ted, that can contribute to render this book worthy of
a continuance of the public favour.
