Brahmi numerals are a numeral system attested in the Indian subcontinent from the 3rd century BCE. It is the direct graphic ancestor of the modern Hindu–Arabic numeral system . However, the Brahmi numeral system was conceptually distinct from these later systems, as it was a non- positional decimal system, and did not include zero .
Among the inscriptions of Ashoka (c. 3rd century BCE) written in the Brahmi script a few numerals were found, which have come to be called the Brahmi numerals. [26] The numerals are additive and multiplicative and, therefore, not place value; [26] it is not known if their underlying system of numeration has a connection to the Brahmi script. [26]
One century later, their use of the symbols that became 2, 4, 6, 7, and 9 was recorded. These Brahmi numerals are the ancestors of the Hindu–Arabic glyphs 1 to 9, but they were not used as a positional system with a zero, and there were rather [clarification needed] separate numerals for each of the tens (10, 20, 30, etc.).
The Hindu–Arabic numeral system is a decimal place-value numeral system that uses a zero glyph as in "205". [1]Its glyphs are descended from the Indian Brahmi numerals.The full system emerged by the 8th to 9th centuries, and is first described outside India in Al-Khwarizmi's On the Calculation with Hindu Numerals (ca. 825), and second Al-Kindi's four-volume work On the Use of the Indian ...
The 2, 8, and 9 resemble Arabic numerals more than Eastern Arabic numerals or Indian numerals. Leonardo Fibonacci was a Pisan mathematician who had studied in the Pisan trading colony of Bugia , in what is now Algeria , [ 15 ] and he endeavored to promote the numeral system in Europe with his 1202 book Liber Abaci :
Southern Brahmi evolved into the Kadamba, Pallava and Vatteluttu scripts, which in turn diversified into other scripts of South India and Southeast Asia. Brahmic scripts spread in a peaceful manner, Indianization, or the spread of Indian learning. The scripts spread naturally to Southeast Asia, at ports on trading routes. [2]
The first examples of the Hindu–Arabic numeral system appeared in the Brahmi numerals used in the Edicts of Ashoka, in which a few numerals are found, although the system is not yet positional (the zero, together with a mature positional system, was invented much later around the 6th century CE) and involves different symbols for units ...
The Brahmi letter , Tha, is probably derived from the Aramaic Teth, and is thus related to the modern Greek Theta. [2] Several identifiable styles of writing the Brahmi Tha can be found, most associated with a specific set of inscriptions from an artifact or diverse records from an historic period. [3]
