Mathematical Treasure: Zhu Shijie’s Introduction to Mathematical Studies

Zhu Shijie (1249-1314) of the Yuan dynasty was one of the greatest algebraists of traditional China. In his Suan xue qi yuan (Introduction to Mathematical Studies, or Primer of Mathematics) of 1299, he presented his tianyuan (celestial) technique of solving algebraic equations. As with many Chinese mathematical classics, the book was lost over time in China; however, it was still known and studied in Korea and Japan. When in the 19th century, the scholar Luo Shilin (1774-1853) resurrected mathematical studies in China, he obtained a Korean copy, which he translated into Chinese for the use of his students. This is a later Chinese copy.
