Abacus calculation is a digital calculation method with abacus as a tool, and it is one of many scientific and technological inventions in ancient China, which evolved from "calculation". The abacus began in the Han Dynasty, matured in the Song Dynasty and flourished in the Yuan and Ming Dynasties. It has been widely circulated in China since the Qing Dynasty.

Abacus calculation is a calculation technique that uses abacus as a tool, based on arithmetic and algorithm, and uses fingering abacus to add, subtract, multiply, divide and square with formulas.

Abacus calculation is a digital calculation method with abacus as a tool. It is an important part of China's traditional culture and one of the earliest mathematical inventions in the world. The abacus originated in ancient China. At first, people used "counting chips", that is, a series of sticks shaped like chopsticks, which gradually evolved into abacus.

The structure of the abacus includes frame, beam, bead and file, in which the frame is the outer frame of the abacus, the beam is the beam in the frame, the bead is the bead in the frame, and the file is a row of grids on the beam. When calculating, people move the beads to different positions, and get the required results through addition, subtraction, multiplication and division.

Abacus calculation is not only a calculation method, but also a symbol of culture and wisdom. It represents the wisdom and creativity of the people of China, and embodies the development level of ancient mathematics and science and technology in China. At the same time, abacus calculation also has a wide range of application values. Widely used in China's economy, finance, commerce and other fields, it became one of the important supports of China's economic development at that time.

With the development of modern science and technology such as computers, abacus has gradually lost its original application value, but as a symbol of cultural heritage and wisdom, it is still cherished and passed down by people. Today, more and more young people begin to learn and inherit abacus skills, and integrate them into modern mathematics education in order to carry forward the excellent traditional Chinese culture.

In today's highly developed era of science and technology, although abacus is no longer the mainstream calculation method, its value and significance can not be ignored. On the one hand, abacus can exercise people's thinking ability and improve the calculation speed and accuracy; On the other hand, abacus is also an intangible cultural heritage, which represents one of the essences of China culture.

Therefore, we should attach importance to and inherit the abacus culture, so that more people can understand and master this unique skill.
