Wang (1768- 1797), a female mathematician, is from Jiangning. She is the daughter of Wang Xichen, a scholar in Qing Dynasty. She wrote one volume, one volume, one volume, four volumes, five volumes, five volumes.

As can be seen from her works, she is a female mathematician engaged in astronomical and computational research. Calculation, also known as financing, strategy, strategy, etc. , sometimes an operator, is a rod-shaped calculation tool. Generally, a group of small sticks with the same length and thickness are made of bamboo or wood, as well as metal, jade, bone and other materials. When not in use, they are put in a special bag or operating cylinder, and placed on a special board, felt or directly on the table. The method of calculation with "calculation" is called "calculation", and the introduction of calculation into Japan is called "arithmetic". Calculation and preparation originated very early in China. There is a saying in Laozi that "those who are good at counting don't need to count". Now the earliest record is Sun Tzu's calculation, which was gradually replaced by abacus in the Ming Dynasty.

/kloc-At the beginning of the 7th century, the British mathematician Napier invented a calculation method, which was introduced to China in the late Ming Dynasty, also known as "calculation". Mei Wending and Dai Zhen, famous mathematicians in Qing Dynasty, studied this. Dai Zhen called it "strategic calculation". Wang also devoted himself to studying this calculation method introduced to China from the west, and wrote three volumes to introduce the western calculation method to Chinese people. In her book, she supplemented and explained the western calculation methods to make them simple and clear. Napier's multiplication and division method introduced by Wang was easier for readers to understand at that time, but it was more complicated than China's multiplication and division method at that time. Therefore, mathematicians have been using China's calculation method instead of Western calculation. Today's readers regard the calculation methods, multiplication and division at home and abroad as antiques, and adopt the four written operations imported from abroad. This kind of written calculation began to be used in 1903, so the history of China's integration with the world is only 100.
