The invention of Arabic numerals:
In fact, Arabic numerals were not invented by Arabs, but by ancient Indians.
Load Arabic numerals.
Ancient Indians carved some horizontal lines on stone tablets to indicate numbers, one horizontal line indicated 1 and the other horizontal line indicated 2 ... Later, they used palm leaves or birch bark as writing materials and connected some strokes, for example, two horizontal lines of 2 were written as z, three horizontal lines of 3 were written as z, and so on.
In the 8th century AD, an Indian mathematician named Kank came to Baghdad, the capital of Arabia, with digital books and astronomical charts. At this time, China's papermaking had just been introduced into Arabia. As a result, his book was quickly translated into Arabic and spread in the Arabian Peninsula, and Arabic numerals also spread to all parts of Arabia.
With the commercial exchanges between the East and the West, these figures were introduced to Europe by Arab businessmen in the12nd century. Europeans love this convenient and applicable notation, and they think it is Arabic numerals, which has caused this historical misunderstanding. Although people later knew the truth of the matter, they never corrected it because they were used to it.
