Arabic digital history

1, 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 them in cells. If there is a symbol in the first cell, such as a dot representing 1, then the same dot in the second cell represents ten, and the dot in the third cell represents one hundred. In this way, not only the digital symbols themselves, but also their position order is of great significance.

3. Indian scholars introduced the symbol of 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.

4. It was spread to other European countries by Pope Gelber Auriac in 10 century. 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.

5. At that time, the shapes of Arabic numerals were not exactly the same as those of modern Arabic numerals, but they were close. Many mathematicians have made great efforts to make it today's 1, 2, 3, 4, 5, 6, 7, 8, 9, 0. Arabic numerals originated in India, but spread to all directions through Arabs, which is why they were later called Arabic numerals.
