Which country invented the abacus

There is no doubt about China!

It is impossible to find out exactly when and by whom the abacus was invented. But its use should be very early. The Eastern Han Dynasty mathematician's "Chronicles of Mathematics" contains:

Abacus control belt four times, longitude and latitude three talents. "Northern Zhou Zhenluan Zhuyun:" Stereotype is three points.

There are five beads each, the upper bead and the lower four beads are different, the beads of different colors are five, and the lower four beads are each one. It can be seen that there was an abacus in the Han Dynasty, but the shape is different from today. However, one bead above the middle beam is five, and each bead below the middle beam is one, which is the same as in modern times.

According to Xu Yue, his teacher Liu Hong once asked the Taoist Mr. Tianmu, who had taught the abacus method, which shows that the abacus had appeared in the Eastern Han Dynasty at the latest. Some historians believe that the name abacus first appeared in the Yuan Dynasty scholar Liu Yin (1249-1293) in the Collected Works of Mr. Jingxiu. In "Yuan Qu Xuan", the anonymous "Pang Juquan mistakenly put the debt", the abacus is also mentioned.

There is such a sentence in the play: "Idle hands, go to the abacus and pull out my age". In 1274 AD, Yang Hui recorded the "Nine Return and Division" about the abacus in "Multiplication and Division" and Zhu Shijie in "Arithmetic Enlightenment" in 1299.

In 1450 A.D., Wu Jing described the usage of the abacus in detail in the "Nine Chapters of Detailed Annotations and Analogous Algorithms". Zhang Zeduan painted an abacus in the "Qingming Riverside Map", which shows that the abacus was widely used in China as early as the Northern Song Dynasty or before the Northern Song Dynasty.

The abacus of our country is made up of antiquity"Calculation". "Calculation" is the use of a bamboo stick as a chip to calculate. At the end of the Tang Dynasty, the improvement of multiplication and division had been seen, and the division song of calculation was produced in the Song Dynasty.

In the middle of the 15th century, there were specifications for making an abacus in the "Luban Mujing". Due to the popularization of the abacus, works on the abacus were also produced, and the most popular abacus book was the "Algorithm Tongzong" compiled by Cheng Dawei in the Ming Dynasty in 1593. Because the abacus formula is easy to memorize and simple to calculate, it has been widely used in China, and has also spread to Japan, North Korea, India, the United States, Southeast Asia and other countries and regions.

The emergence of the abacus is known as a major reform of the calculator in human history, and it is still playing its unique role today, when the electronic calculator is prevalent.

Folklore also claims about the invention of feathers, which are of course inaccurate.

Resources.

The abacus is also a great invention in ancient China. The Chinese abacus evolved from the ancient "calculation". "Calculation" is the use of a bamboo stick as a chip to calculate.

At the end of the Tang Dynasty, the improvement of multiplication and division began to be seen, and the division song of calculation was produced in the Song Dynasty. In the literary and dramatic works of the middle and late Yuan Dynasty, the abacus is mentioned. In the middle of the 15th century, there were specifications for making abacus in the Lubanmu Sutra.

Around the end of the Ming Dynasty, the abacus gradually became popular. The most popular abacus is the "Algorithm Tongzong" compiled by Cheng Dawei in the Ming Dynasty in 1593. Because the abacus formula is easy to memorize and easy to calculate, it is widely used in China, and has also spread to Japan, North Korea, India, the United States, Southeast Asia and other countries and regions, and is widely welcomed.

The advent of the abacus is known as a major reform of computing machines in human history. At present, tens of millions of people in China's finance and trade, industry and agriculture, and various enterprises are still using abacus.

In 1981, China successfully developed an electronic abacus, the upper half of which uses a micro-integrated circuit and the lower half is an abacus. According to the fast addition and subtraction abacus and the superior characteristics of the multiplication and division electronic computer, it is integrated into a whole, multiplying and dividing with the upper half, and adding and subtracting with the lower half, thus greatly improving the efficiency of the abacus. This innovation is the result of the combination of ancient culture and modern science, proving that abacus can still perform its calculation function and achieve a more perfect state when the abacus is renewed.

Invented in China, of course. There are not many other countries that use abacus.

The country where the abacus was invented was China, and the invention time was probably about 2,600 years ago in the Eastern Zhou Dynasty.

The abacus is a traditional Chinese calculation tool, which gradually evolved from the calculation that has been commonly used as early as the Spring and Autumn Period, and it is not only an important invention in ancient China, but also a calculation tool that was widely used by people before the appearance of Arabic numerals.

China is the hometown of the abacus, and today, when computers have been widely used, the ancient abacus has not only not been abandoned, but is still favored by many people because of its convenience and accuracy.

China was the first country to invent and use it, about 2,600 years ago during the Eastern Zhou Dynasty.

The abacus is a calculation tool that everyone is familiar with, but what is the exact year of its invention? From Xu Yue's work "Records of Mathematics" in the Eastern Han Dynasty, we first saw the word "abacus". However, the note says that it can only do addition and subtraction.

Today, this seems to be a prototype of an abacus at most. According to the analysis of available reliable data, the abacus was invented in the Song and Yuan dynasties. Cheng Dawei's work Zhizhi Algorithm Tongzong (1592) was one of the most widely circulated and influential works of the time devoted to abacus.

The abacus is one of the major scientific achievements of ancient China. It has the advantages of simple structure, simple operation and easy carrying, so it has been widely used and has lasted for a long time. To this day, abacus is still a compulsory subject for primary school students in China.

Although all kinds of electronic computers and electronic calculators have become quite popular in the market, when it comes to addition and subtraction, their calculation speed is still not as fast as that of the abacus in the hands of skilled operators of abacus.

After the abacus showed its skills in China, it spread across the ocean to Korea, Japan, Southeast Asia and Arabia, making important contributions to world civilization.

The abacus is an invention of ancient China and a classical computer in China.

The abacus is the earliest calculation tool in China and the prototype of the computer.

The abacus was called the abacus before the Ming Dynasty, it was calculated by the clever ancient people with a small wooden stick, and then the number calculated became larger and larger, the small wooden stick was too slow to calculate, people put some beads on it, a grand number was prescribed to calculate how much, it became an abacus, to the Ming Dynasty, the abacus can not only calculate the number, but also can be used as a feng shui instrument villain, the abacus is a great invention of the Chinese in arithmetic technology, not only in China, many countries in the world have been widely used. It is a great invention of the Chinese in arithmetic technology, and it is widely used not only in China, but also in many countries around the world. Sparrows.

What is an abacus, and what is invention in our country? What are the four abacus, and what is the invention in our country? What is the abacus of the four major inventions, and what is the invention of our country? The abacus is one of the four major patterns of staring and slowing down.

The abacus is an ancient invention in our country, and we can use it to calculate and make feng shui supplies. In ancient times, people used small wooden sticks to calculate the wild game, and these small wooden sticks were called"Calculate the chips", using the calculation chip as a tool to calculate the cluster laughed"Calculation"Song Zheng Rang. Later, with the development of production, the use of small wooden sticks for calculations was limited, so people invented a more advanced calculation tool - the abacus.

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 by the Chinese on the basis of long-term use of arithmetic chips. In ancient times, people used small wooden sticks to make calculations, and these small wooden sticks were called"Calculate the chips", calculations performed with a chip as a tool are called"Calculation"。Later, with the development of production, the use of small wooden sticks for calculations was limited, so people invented a more advanced calculator - the abacus.

The abacus is rectangular, surrounded by a wooden frame, in which are fixed a small wooden stick, the small wooden stick is wearing wooden beads, a beam in the middle and the abacus is divided into two parts, the upper half of each wooden stick has two beads, each bead is five, the lower half has five beads, each bead represents one.

The origin of the abacus.

As for the origin of the abacus, it can be traced back to 600 B.C., and it is said that there was one in China at that time"Abacus"。The ancients strung 10 abacus beads into a group, arranged them in groups, put them into the frame, and then quickly dialed the abacus beads to calculate. At the end of the Eastern Han Dynasty, Xu Yue recorded in the "Records of Mathematics" that when his teacher Liu Hong visited the hermit Mr. Tianmu, Mr. Tianmu explained 14 calculation methods, one of which was the abacus, and the calculation tools used were very close to the modern abacus.

Each of these abacus has 5 movable beads, with the top 1 being equal to 5 and the bottom 4 being treated as 1 each.

With the use of abacus, people have summed up many calculation formulas, making the speed of calculation faster. This method of calculating with an abacus is called abacus. In the Ming Dynasty, abacus could not only do addition, subtraction, multiplication and division, but also calculate the land area and the size of various shapes and things.

Because the abacus is simple to make, cheap, easy to memorize, and simple to calculate, it is widely used in China and has spread to Japan, North Korea, the United States and Southeast Asia and other countries and regions.

Now, it has entered the era of electronic computers, but the ancient abacus still plays an important role. In China, there are a number of prudent masters in all walks of life. The use of abacus and abacus, in addition to the convenience of calculation, also has the effect of exercising thinking ability, because the planning disk requires the close cooperation of the brain, eyes and hands, which is a good way to exercise the brain.
