Preface to the revised edition

The Chinese original, Text on Mathematics (算學啓蒙) , was compiled by Zhu Shijie (朱世傑) in 1299 in the Yuan (元) Dynasty of China, and was composed of 20 chapters and 259 problems. As implied in the title of the book, it was an introductory beginning textbook for laymen and written in common language. The author, Zhu Shijie (1249–1314), courtesy name Hanqing (漢卿), pseudonym Songting (松庭), was one of the greatest Chinese mathematicians during the Yuan Dynasty. In addition to Text on Mathematics, Zhu Shijie also wrote Precious Mirror of the Four Elements (四元玉監) and made a remarkable contribution to mathematics in China.  

Interestingly, all later versions of Zhu Shijie’s Text on Mathematics were based on Korean versions, as the book  became lost in China during the Mind dynasty until the Qing dynasty mathematician Luo Shilin (羅士琳) obtained a Korean printed edition of the book in Liulichang (琉璃廠), Beijing, and re-printed in Yangzhou. Since then, the book was reprinted in China several times.

The book was widely used as an introductory text during the Joseon dynasty along with the Yang Hui Arithmetic (楊輝算法) and the Xiang Ming Arithmetic (祥明算法).
