Rakam Bir 1

The Arabic digit one belongs to the numerals which are widely spread around the planet. This positional counting system appeared in India in the 5th century or even earlier. The Arabs borrowed it from the Indians. Al-Khwarizmi wrote a book called “On the Indian Calculation,” which helped to spread the Arabic digits. Later this counting system came to Europe through Spain. Pope Sylvester II advocated for the replacement of Roman numerals with Arabic ones in the 10th century. In the 12th century, Al-Khwarizmi's book “On the Indian Calculation” was translated into Latin, which played an important role in the adoption of Arabic numerals.
