Ah, how many years BC was the Rab number invented?

Around 500 AD, with the rise and development of economy, culture, and Buddhism, the Punjab region in the northwestern part of the Indian subcontinent was at the forefront of mathematics. The astronomer Ayebiheit made a new breakthrough in simplifying numbers: he wrote down numbers in cells, and if there was a symbol in the first cell, such as a dot representing 1, then the same dot in the second cell would represent ten, and the dot in the third cell would represent a hundred.

In this way, not only the number symbols themselves, but also the order in which they are located are also important. Later, Indian scholars introduced the symbol as zero. Suffice it to say that these symbols and representations are the ancestors of today's Arabic numerals.

Arabic numerals were invented by Indians in the 3rd century AD and spread to Arabia in the 7th century.

From 2000 BC to 1000 BC, the Aryans who settled in the upper Indus River valley realized that numbers were needed for computing in production and life, so they created simple number symbols. By around 300 BC, Brahmanical figures appeared in India. There was no "0" at that time.

0", which was a black dot at the time. It took hundreds of years of evolution before the "0" was written. In this way, a complete set of ten-digit numbers is formed.

Invented by the Indians! 1st century A.D.!

Arabic numerals were originally recorded in a grid with symbols, corresponding to the position, and then took on the numerical meaning, although they are called Arabic numerals, but in fact they were invented by Indians.

Arabic numerals originated in ancient India because of the design and planning of urban construction, as well as the need to calculate the movement of the sun, moon and stars during sacrifices.

Arabic numerals were invented by ancient Indians, and there is no record of who invented them in history. Arabic numerals are produced in India.

Arabic numerals were first invented by ancient India.

Arabic numerals that have been adapted by Westerners or Europeans. The Arabic numeral system was first invented by the Arabic Brahmi and later introduced to the West by Arabia.

Many regions have quoted this system, but they have all adapted it to their own script, so in fact, there are many kinds of numeric characters called "Arabic numerals", and the Arabic numerals that are commonly believed to be the set of Arabic numerals of Westerners.

The modern Arabic numerals are based on the decimal system and use a total of 10 counting symbols. Take the place value method, the high position is on the left, the low position is on the right, and the writing is from left to right.

With the help of a few simple mathematical symbols (decimal points, minus signs, etc.), this system can unambiguously represent all rational numbers. In order to represent very large or extremely small numbers, scientific notation was created on the basis of Arabic numerals.

Arabic numerals are also generally used to represent numbers in other decimal systems, and some numbers are selected or a few numbers are added. Arabic numerals originated in Arabia (but there were no zeros at the time), hence the name. It has become the most widely used counting system and is used all over the world.

The above content refers to Encyclopedia - Arabic numerals.

Arabic numerals were not invented by the Arabs, although it has Arabic in its name, Arabic numerals were invented by Indians. Many people mistakenly think that Arabic numerals were invented by the Arabs, hence the name, but in fact, the real inventor is an Indian mathematician. And the Arabs spread this invention widely, and the people with them did not know who the real inventor was, so they called this kind of number Arabic numerals.

Just like snow peas, we Chinese call this kind of bean snow bean, but the Dutch call this kind of bean Chinese bean, which shows that it is not what the name is, it must belong to whom. To get back to the point, the first Indian mathematician invented Arabic numerals, honestly conducted mathematical research at home, who knew that the Arabs suddenly caught him in Baghdad, located in Arabia, Baghdad is a village on the west bank of the Tigris River, "Baghdad" Chinese interpretation meaning is "heaven-given". Arabs want to learn advanced mathematics to help their development.

So then the Indian mathematician was forced to teach them mathematics, this advanced and convenient mathematical symbols and systems began to be popularized in Arabia, this way greatly improved the efficiency of transactions, made communication simpler, and made Arabs more popular.

Since then, Arabic numerals have become world-famous and widely accepted, and are used all over the world, with a wider and deeper influence than the English language. Today's financial bookkeeping, in addition to the convenience of using Arabic numerals, but also to ensure safety, combined with our traditional "one two three Wu Lu Qi Jiu pick" counting method, is more secure. The two work together to make our lives convenient and safe.

Egg 0, Bangbang 1, Goose Goose 2, Twist 3, Red Flag 4, Crane 5, Warp 6, Knife 7, Circle 8, Balloon 9", do you remember this familiar nursery rhyme? Remembered the familiar one, right? But do you know who invented them?

How did they get around us?

Were Arabic numerals invented by the Arabs? You may say, "Of course, how else can the calendar be called Arabic numerals?" In fact, Arabic numerals were not invented by the Arabs, but by the ancient Indians.

In ancient times, Indians would carve some simple lines on a board to represent simple numbers, for example, one horizontal for 1, two horizontal for 2 ......Later, they found it inconvenient to write these symbols on the leaves or bark of trees, and accidentally connected some strokes, for example, to write the two horizontal lines for 2 as "z" and the three horizontal lines for 3 as "彐".

In the 8th century A.D., a mathematician in India traveled to Arabia with a caravan with books on mathematics. It was at this time that Chinese papermaking was also introduced to Arabia. People were intrigued by the novelty of the figures, so the books he brought with him were quickly translated into Arabic, reprinted many times, and quickly spread throughout the Arabian Peninsula.

Because of the convenience and conciseness of the expression of this number, Arabic numerals were widely used by the Arabs.

Over time, after the discovery of sea lanes, Arab merchants spread Arabic numerals to Europe in the course of their trade. At the beginning, the Arabic numerals were different from the present, but in the subsequent circulation and use, the appearance of the Arabic numerals also changed for the first time, and finally the writing of these numbers was the same as the current one.

So why is it still called Arabic numerals? It turned out that after Arabic numerals were transmitted to Europe, Europeans quickly became accustomed to using these simple, easy-to-use counting symbols, and they thought that they were numbers created by the Arabs, so they called these numbers Arabic numerals. Later, it became known that it was not actually created by the Arabs, but because it was used to being called "Arabic numerals", it was not corrected.

Because the Arabic manuscript is concise, clear and easy to use, it has gradually spread to the world and is used by countries all over the world.

Hey, what's the thing on the following **?

You don't know that, do you? This is actually also an Arabic numeral.

In Arab countries such as Egypt, most of them have two sets of number notation. One is the Arabic numerals that everyone uses nowadays, and the other is the counting method that only they use themselves, which is the number in the picture above, which is often referred to as "Arabic numerals". But foreigners living in Arabia, they are not familiar with "Arab numbers".

In order to make it easier to remember these strange "Arabic numbers", they made up a lot of mantras, such as "upside down, seven up and eight down", etc.

Well, I didn't expect that the Arabic numerals we meet every day also have so many mysteries. Children, how much have you memorized?

Arabic numerals were invented by the Indo-Yamakai people.

In the 3rd century AD, a scientist in ancient India, Baghdad, invented Arabic numerals. The oldest counts were probably up to 3, and in order to conceive the number "4", it was necessary to add up 2 and 2, 5 was 2 plus 2 plus 1, and 3 was obtained from 2 plus 1, and it was probably later that the number 5 represented by the handwritten five fingers and the number 10 represented by the ten fingers of both hands appeared. This principle is actually the basis of mathematical calculations.

The Roman count consisted only of numbers up to (i.e., 5), and numbers up to (i.e., 10) were combined with (5) and other numbers. is a combination of two that have different quantities of the same symbol depending on its positional relationship with other symbols. Thus began the concept of numerical position, and this important contribution in mathematics should be attributed to the ancient inhabitants of the two river basins, and later the ancient bream people improved on this basis and invented the ten symbols 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 to express the number, which became the basis of numeration.

The oldest engraving records with the symbol of zero appeared in India in the eighth century. At that time, zero was called the head of that.

History. Later, the Arabs introduced this figure to Spain. In the 10th century, it was spread to the rest of Europe by Pope Gerbert Aurillac.

Around 1200 AD, European scholars formally adopted these symbols and systems. By the 13th century, under the initiative of the mathematician Fibonacci of Pisa, Italy, the Europeans of Puho Paiton also began to adopt Arabic numerals, and this phenomenon was quite common in the 15th century.

At that time, the shape of Arabic numerals was not exactly the same as modern Arabic numerals, but they were relatively close, and many mathematicians took a lot of effort to make them the way they were written.

Arabic numerals, which are used as standard numbers in countries around the world.

Arabic numerals were not invented by Arabs but by Indians, and should actually be classified as an Indian language. In 700 A.D., the Arabs united in Islam conquered the surrounding peoples and founded the eastern part of India, and around 700 years ago, the Arabs conquered the Punjab region, and they were surprised to find that the conquered areas were more advanced in mathematics than they were.

Later, the Arabs introduced these numbers to Spain and other countries of faith, and Arabic numerals originated in India but were transmitted to the Quartet through the Arabs, which is why they came to be called Arabic numerals.

1. In the 3rd century AD, an Indian scientist in Baghdad invented Arabic numerals. The oldest counts are probably up to 3, and in order to conceive the number 4, it is necessary to add 2 and 2, 5 is 2 plus 2 plus 1, and the number 3 is obtained from 2 plus 1, and it is probably later that the number 5 is represented by handwritten five fingers.

2. Arabic numerals were invented in India, and the reason why they are called Arabic numerals is that the influence of the Indian state was very small at that time, and later the Arab Empire was established, which popularized this number, and spread to Spain and the world, so this title has been handed down.
