Origin of Arabic Numbers
The numbers that are used worldwide are basically Arabic numbers. During the 8th century when an Indian Gastronomist came to the Almansour royal palace with a book “Sod Hanta” (about astronomy and mathematics) written by Brahma Jobta, Almansour ordered to translate the book into Arabic and explore more sciences.
1, 2, 3, 4, 5, 6, 7, 8, 9
In designing the Arab numbers, Al Khawarizmi based his choice of a particular form on the number of angles that each number should contain. For instance, the number one contains only one angle, number two has two angles, and number three includes three angles, ects… The arabs popularise these algorithms, but their origin goes back to the phenecian merchants that used them to count.
And the most interesting and intelligent of all….. Zero has no angle !
