       Abacus in our country has a long history, it actually from when? Who invented There is no definite conclusion. Some  scholars believe that abacus originated in the Han Dynasty; some people  think that produced in the Song and Yuan Dynasties. From  the beginning of some maths, the early Southern Song Yang Hui "take the  passage of change through the end", the Yuan Dynasty Zhu Shijie's  "Enlightenment", or the Yuan Dynasty "Ding Ju algorithm" and so on, have  a very complete return song tactics. From  the Tongmeng reading "new relative to the four words" to see, the above  has been painted "abacus", the figure nine files, Liang Liang,  according to close Mr. Zhang Zhigong research, is a beginning of the  book. This book provides strong evidence for the development and widespread use of Abacus.

       It  is proud to be proud of the rise in the abacus to gradually improve the  process of the Yuan Dynasty Xingtai Guo Bo Yu made a great  contribution. Ling  Yang algae "Li spoon compiled" records: "Yuan beginning (Yuan Shun  emperor, AD 1333) made" big calendar ", visit Guo Bo Yu good to Zuo  Cheng." Qingmei Wending " Test  "records:" Guo Bo Yu Although the descendants of Guo Taishi, but  seclusion in the people and not the official, its multiplication and  division algorithm, the people can be sure. Guo Taishi, is Guo Shoujing  (now Xingtai City, established Guo Shoujing Memorial Hall) For the history of the history of the British famous scientist  Joseph Needham with the "history of Chinese science and technology",  when it comes to the abacus, also mentioned Guo Bo Yu.

       Guo Bo Yu was born in a mathematician home. His predecessors Guo Rong (Shoujing grandfather), "Xingtai County" that he "through the five class, good at count, water." Guo  Shoujing is a well-known Chinese astronomer, mathematician, water  conservancy engineering scientist, his high mathematics, spherical  geometry, triangle has a deep knowledge. And even some scholars think he is the founder of spherical geometry, the milestone of the development of Chinese mathematics. Living  in this family environment Guo Boyu, childhood love of mathematics,  especially for simple, efficient abacus, but also cause his interest in  research, so Guo Shoujing died only 17 years, he can use the abacus, to  help develop its digital, (1333-1335)  to build a "big calendar", then abacus multiplication and division of  law has been widely circulated in the folk, we can see Guo Beiyu in the  abacus on the achievements of the study, so that the so-called "big  calendar", which we can see, Yuan Dynasty Yuan Dynasty (1333-1335) Was known as the Yuan Dynasty "big abacus".

        Abacus  after the rise of our country, about the beginning of the Ming Dynasty  to Japan, North Korea and Southeast Asia and other countries to spread,  and later in Japan and other countries have a big development. The recent abacus is popular in the West, as a "new culture" to be  introduced, so that the ancient abacus in the world to further promote  and develop.
