Xu Yue
Xu Yue was a 2nd and 3rd century Chinese mathematician. He is traditionally known as the author of Shushu Jiyi ( Remarks on the Tradition of Arithmetic-Numerological Methods ), which, according to recent mathematicians, is probably apocryphal . It is part of the ten mathematical classics ( Suanjing shi shu ).
Xu Yue was from Donglai in what is now Shandong Province .
According to Jean-Claude Martzloff, the mathematical content of Shushu Jiyi is difficult to interpret and obscure, also taking into account the commentary by Zhen Luan. It contains explanations about the power representation of large numbers and different number systems, numerological and difficult to understand theological (Buddhist and Taoist ) explanations. Some terms allude to the I Ching . It is likely from a later writer who used Xu Yue's name to gain respectability. For example, he gives representations of numbers with different orders of magnitude as the base ( , , ) After his commentator Zhen Luan he also described a magic square with side length 3. He described a computing device with balls ( abacus ).
Xu Yue was a student of the calendar expert Liu Hong and was like him at the Imperial Observatory. A commentary on the Nine Chapters of Arithmetic ( Jiu Zhang Suanshu ) is said to have originated from Xu Yue , which has not survived, but is said to have been written before Liu Hui's commentary .
