The structure and mechanical nature of traditional Chinese mathematics were based on position (wei位) and pictograph (hsiang象). All steps and ca1culations using an abacus (or more primitive calculating device), involved a combination of position and pictograph. Once the decimal system of calculation was devised, the unique characterist of the organization and mechanics of ancient Chinese mathe­matics appeared, decimal system of China was a natural product of the Chinese language’s monosyllabic and isolating features as well as the ideographic characteristic of the written language. Chinese characters are based on an ideographic writing system in which the shape and structure of a character symbolizes an object and can also convey abstract ideas. The Chinese language frequently relies on concrete phrases to convey abstract thoughts. This kind of symbolic language and writing system influenced the language of ancient Chinese mathematics. The external structure of position and pictograpn in traditional mathematics were also influenced by the I-Ching. The 64 “kua” (or divinatory diagrams) are symbols made up by placing the two diagrams Yin and Yang in different positions.
