With an appendix, containing a series of queries on bills and merchants accounts, and a course of letters on business; also duodecimals, timber-measuring, artificers computations, and the square and cube root, with their application. This book, "A Concise System of Commercial Arithmetic, Adapted to Modern Practice", by James Morrison, is a replication of a book originally published before 1838. It has been restored by human beings, page by page, so that you may enjoy it in a form as close to the original as possible.
