Who invented the abacus? Invented in a few years

Inventor of abacus: Liu Hong.

Liu Hong, whose name is Yuan Zhuo, was born in Mengyin County, Taishan County, Eastern Han Dynasty (now Mengyin County, Linyi City, Shandong Province), and a descendant of Liu Xing, King of Lu in the Eastern Han Dynasty.

Many arithmetic scholars believe that the birth of the abacus can be pushed back to the Tang Dynasty. Because of the continuous wars during the Five Dynasties and Ten Kingdoms period before the Song Dynasty, the development of science and technology and culture was relatively sluggish, and it is less likely that the abacus was born at this time. The Tang Dynasty was a prosperous era in Chinese history, with a relatively developed economy and culture, and new calculation tools were needed, so it is very likely that the abacus that was used in 2000 evolved into an abacus, and the abacus was invented in the Tang Dynasty.

The inventor is no longer verifiable.

The abacus was first invented by Xu Yue, a mathematician at the end of the Eastern Han Dynasty. The word "abacus" was first seen in the "Records of Mathematics" written by Xu Yue in the Eastern Han Dynasty, in which there is a cloud: "The abacus controls the four times, and the longitude and latitude are three talents."

The gist is: the wooden board is carved into three parts, the upper and lower parts are used for stopping the beads, and the middle part is used for positioning. Each person has 5 beads, and the upper bead and the lower four beads are distinguished by color, which is later called "file".

One bead on the top is five, and four beads on the bottom are one for each bead. China's abacus evolved from the ancient "calculation". Due to the convenience and speed of the abacus calculation, it has been a common calculation tool used by the working people of ancient China for thousands of years, and even the most advanced electronic calculators in modern times cannot completely replace the role of the abacus.

The United Nations Educational, Scientific and Cultural Organization (UNESCO) has just adopted the abacus in Baku, the capital of Azerbaijan, and the abacus has officially become an intangible cultural heritage of humanity. This is also the 30th item listed as intangible cultural heritage in China.

When was the abacus invented and by whom?

The inventor of the abacus was Liu Hong, who was in the Spring and Autumn Period. It has a history of more than 2,000 years.

If you're satisfied, remember!

Who invented the abacus and which dynasty it originated from, there is still a debate in the academic circles, and there is no definite evidence so far

First, the Eastern Han Dynasty and the Northern and Southern Dynasties said.

Second, Yuan Ming said.

Third, Tang Song said.

The abacus is a traditional Chinese calculation tool. The invention of the Chinese on the basis of long-term use of arithmetic chips is a great and important invention in ancient China, and it was a widely used calculation tool all over the world before the emergence of Arabic numerals.

It is important to note that the term abacus does not refer specifically to the Chinese abacus. Judging from the existing documents, many ancient civilizations have their own calculation tools similar to abacus. All kinds of abacus in ancient and modern China and abroad can be roughly divided into three categories: sand table, abacus, and bead-piercing abacus.

Please refer to it.

When was the abacus invented.........What exactly is the abacus invented, now ash can not be investigated, but its use should be very early, the Eastern Han Dynasty, mathematician Xu Yue (mathematical records) contains: abacus control belt four, longitude and latitude three cai, the Northern Zhou Dynasty Zhen Luan Zhuyun: stereotype for three points, each five beads, the upper bead and the lower four beads of color difference, the pearl of different colors when five, its 7l four let people each be ......

There is no record in the history books, the earliest real abacus is found in the Northern Song Dynasty Zhang Zeduan's version of the Qingming Shanghe map, the former Qin unearthed the calculation chip, with a small wooden stick counting, such as Zhongshan Kingdom, to the Han Dynasty also used a small wooden stick, unearthed cultural relics such as the Mancheng Han tomb. Going back to the end of the New Era, the knotted rope chronicle.

The abacus was invented by Xu Yue in the Eastern Han Dynasty, and this invention greatly improved the speed of operation.

The reliable statement is that during the reign of Emperor Ling of the Eastern Han Dynasty, Liu Hong invented it.

The abacus is an invention in ancient times, and it is the invention of China's own people, but the specific invention of this person has not been found, because this abacus is also constantly developing before it was finally finalized.

The great inventions of antiquity were also helpful for the study of computing technology.

The "abacus" was invented in the 15th century and was invented by Xu Yue. The abacus is a form of manual operation calculation aid, which originated in China and has a history of more than 2,600 years, and is an important invention in ancient China. Before the advent of Arabic numerals, the abacus was a widely used calculation tool in the world.

Today, abacus continues to be used in parts of Asia and the Middle East, especially in stores, where it can be bought from stores of Chinese and Japanese goods. In the West, it is sometimes used to help children understand numbers, and some mathematicians like to experience what it's like to use an abacus to calculate simple arithmetic problems.

Abacus is a tool for performing calculations with an abacus. The invention of abacus has made a leap forward in people's computing ability, and the term "abacus" was first seen in the book "Mathematical Notes" written by Xu Yue, a native of the Eastern Han Dynasty and Wei Dynasty. Xu Yue said in the book:

Liu Huiji, erudite and biased towards mathematics? There are still many kinds of articulation, one of which is abacus. "The Liu Huiji that Xu Yue said is Liu Hong.

Some people say that Mengyin is the hometown of abacus, and Liu Hong is the father of abacus and is respected as a "saint of abacus". Abacus is one of China's five great inventions.

There is a beam through the abacus.

During the Song and Yuan dynasties, mathematicians represented by Yang Hui and Zhu Shijie created various simple methods of multiplication and division and "song formulas" in practical mathematics, which became an important part of abacus arithmetic algorithms. At the same time, the abacus with a beam through the file has been widely used in the people. Therefore, during this period, the abacus had further development in terms of both calculation tools and arithmetic algorithms.

When exactly did the modern abacus originate, due to the lack of literature, researchers on the history of abacus have different opinions, and they are inconsistent. Based on the inferences of various schools, there are mainly Han Dynasty theories, Tang Dynasty theories, Song Dynasty theories, and late Yuan and early Ming Dynasty theories.

The main basis for holding the theory of the end of the Yuan Dynasty and the beginning of the Ming Dynasty is that the abacus is mentioned in the literary and dramatic works of the middle and late Yuan Dynasty. For example, in the sixteenth year of Yuan Shizu (1279 AD), Liu Yin had a five-character poem about abacus in his "Anthology of Mr. Jingxiu".
