176 pp. "This work has been prepared more especially for advanced classes, and is designed for those who have first been well taught in the primary book, and for such as are pursuing the study of written arithmetic, or algebra, and who have never been thoroughly exercised in this branch of study.

Particular attention is invited to the subjects of Fractions, Percentage, and Interest; their treatment is peculiar, and adapted to obviate any of the difficulties, and greatly abbreviate most of the operations in them."--preface
