Sunzi Suanjing ({{zh|s=孙子算经|p=Sūnzĭ Suànjīng|w=Sun Tzu Suan Ching|l=The Mathematical Classic of Master Sun/Master Sun's Mathematical Manual}}) was a mathematical treatise written during 3rd to 5th centuries AD which was listed as one of the Ten Computational Canons during the Tang dynasty. The specific identity of its author Sunzi (lit. "Master Sun") is still unknown but he lived much later than eponymous Sun Tzu, author of The Art of War. From the textual evidence in the book, some scholars concluded that the work was completed during the Southern and Northern Dynasties.{{refn|For instance, in problem 33 of volume 3, it is written, "Luoyang is 900 li away from Chang'an". As the name "Chang'an" was first employed during the Han dynasty, this work could not have been written before the 3rd century. Additionally, in problem 3 of volume 3, Sun Tzu writes "We have a board game, 19 rows and 19 columns square. Question: how many stones are there?" Since go made its first appearance in the mid-3rd century, the work was most probably written during the Wei or Jin dynasties.[1]}} Besides describing arithmetic methods and investigating Diophantine equations, the treatise touches upon astronomy and attempts to develop a calendar.{{citation needed|date=August 2016}} ContentsThe book is divided into three chapters. Chapter 1Chapter 1 discusses measurement units of length, weight and capacity, and the rules of counting rods. Although counting rods were in use in the Spring and Autumn period and many ancient books on mathematics such as Book on Numbers and Computation and The Nine Chapters on the Mathematical Art, but no detail account of the rules were given. For the first time, The Mathematical Classic of Sun Zi provided a detail description of the rules of counting rods: "one must know the position of the counting rods, the units are vertical, the tens horizontal, the hundreds stand the thousands prostrate".[2] Followed by the detailed layout and rules for manipulation of the counting rods in addition, subtraction, multiplication, and division with ample examples. Chapter 2Chapter 2 deals with operational rules for fractions with rod numerals: the reduction, addition, subtraction, and division of fractions, followed by mechanical algorithm for the Extraction of Square root.[3] Chapter 3Chapter 3 contains the earliest example of Chinese remainder theorem, a key tool to understanding and resolving Diophantine equations. {{clear}}BibliographyResearchers have published a full English translation of the Sūnzĭ Suànjīng:
