"Mukza-Chip" was written by Sonching KYONG in 1688 in Korea, and "Warizan-Sho" was written by Shigeyoshi MORI in 1622 in Japan. The former is about a method of calculating with rods, which was influenced by "Suanxue Qimeng" (1299), a mathematical classic in China. The latter is about method of calculating with the abacus, influenced by "Sanfa-Tongzong" (1592) in China. While calculating with an abacus in Japan, it is necessary to recite the division table. The reciting voice was called "WARIGOE" (division voice). In Korea, while calculating with rods, it is necessary to think in peace and quiet, so there is not any voice. KYONG called this silence "MUKZA". KYONG and MORI were both deeply influenced by Chinese mathematics, but their attitudes to Chinese mathematics were very different. KYONG laid stress on traditional methods, and MORI sought new discoveries. KYONG handed on systematic methods and MORI adopted only practical ones.
