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] But in the second half of the first millennium CE, some inscriptions in India and Southeast Asia written in scripts derived from the Brahmi did include numerals that are decimal place value, and constitute the earliest existing material examples of the Hindu–Arabic numeral system, now in use throughout the world.[27] The underlying system of numeration, however, was older, as the earliest attested orally transmitted example dates to the middle of the 3rd century CE in a Sanskrit prose adaptation of a lost Greek work on astrology.[28][29][30]
