Author(s): 
Frank J. Swetz (Pennsylvania State University)

Sankei kyusho is a book of unknown authorship and date that is organized like and obviously influenced by the Chinese mathematical classic, Jiuzhang suanshu (The Nine Chapters on the Mathematical Art). In Sankei kyusho, the Japanese word kyusho means "nine chapters." The book concerns various practical mathematical applications. The opening page immediately focuses on solving problems.

Different geometrical situations involving measurement and calculation are considered.
