Digital introduction:
There are several kinds of numbers, and Arabic numerals are the most common one. Arabic numerals were not invented by Arabs, but by Indians. In fact, it should be listed as Hindi, but it spread to Arabia first and then to the world, so it is called Arabic numerals. Numbers are written symbols used to represent numbers. Different counting systems can use the same number.
The history of Arabic numerals:
Around 500 AD, with the rise and development of economy, culture and Buddhism, Punjab in the northwest of Indian subcontinent has been in a leading position in mathematics, which originated in India. Astronomer Ayepihite made a new breakthrough in simplifying numbers: he recorded numbers in a grid, if there were symbols in the first grid, such as the point representing 1.
Then the same point in the second cell means ten and the point in the third cell means one hundred. In this way, not only the digital symbols themselves, but also their position order is of great significance. Indian scholars also introduced the symbol zero. It can be said that these symbols and representations are the old ancestors of Arabic numerals today.
About 700 years ago, the Arabs conquered Punjab, and they were surprised to find that the mathematics in the conquered area was more advanced than theirs. Later, Arabs introduced this figure to Spain. In 10 century, it was spread to other European countries by Pope Gelber Auriac. Around 1200, European scholars formally adopted these symbols and systems.
In the13rd century, at the initiative of Fibonacci, a mathematician in Pisa, Italy, ordinary Europeans also began to adopt Arabic numerals, which was quite common in the15th century. At that time, the shape of Arabic numerals was not exactly the same as that of modern Arabic numerals, but close to it. In order to make it become the writing style of 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 today.
Many mathematicians have spent a lot of effort. Arabic numerals originated in India, but spread to all directions through Arabs, which is why they were later called Arabic numerals.
