Knowra Arabic numerals Arabic numerals Arabic numerals are the ten symbols 0 through 9 used to write numbers in the Hindu–Arabic decimal system. Their place-value arrangement lets a small set of symbols represent arbitrarily large numbers.
Decimal numeral system : A positional numeral system that represents numbers using powers of ten and the digits 0 through 9. Arabic numerals are the standard symbols used to write numbers in this base-ten system.
Brahmi numerals : An ancient Indian numeral system whose symbols are among the historical ancestors of modern digits. Early forms of the digits developed from numeral traditions in India, including Brahmi.
Roman numerals : A numeral system using Latin letters such as I, V, X, L, C, D, and M. Unlike Arabic numerals, Roman numerals lack positional place value and a zero digit.
Arabic numeral system in computing : The representation and processing of decimal digits in digital computing systems. Computers encode and manipulate the same decimal symbols through character standards and numeric formats.
Place-value notation : A notation in which a digit’s position determines its contribution to the number’s value. The same Arabic numeral has different values in positions such as units, tens, and hundreds.

Unicode : A character encoding standard that assigns code points to text characters across writing systems. Unicode distinguishes Western and other decimal digit characters despite their related uses.
Zero : The number representing no quantity, also used as a placeholder in positional notation. Zero both names a number and marks empty place values in written numerals.
Indian mathematics : The mathematical traditions developed in the Indian subcontinent across many centuries. Indian mathematicians developed the decimal place-value system that gave the numerals their structure.
