Westerners call these numbers Arabic numerals because they first came into contact with Arabs and used these data, mistakenly thinking that they invented them, which has caused this historical misunderstanding.
Later, with the wide spread in the world, everyone agreed with the term "Arabic numerals", which made people in many parts of the world mistakenly think that numerals were invented by Arabs. In fact, Arabs first began to use numbers widely.
After it spread to Europe, Europeans liked this convenient and applicable notation very much. Although people later learned the truth, they never corrected it because they were used to it.
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 has made a new breakthrough in simplifying numbers. He recorded the figures in the grid. If there is a symbol in the first grid, such as a point representing 1, then the same point in the second grid represents ten, and the point in the third grid represents one hundred.
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.
