Numeral system

A numeral is a written word, symbol, or group of symbols that represents a number. The numerals "1, 2, 3, 4, 5, ..." are Arabic numerals, differing from Roman numerals "I, II, III, IV, V, ..." but they represent the same numbers. Similarly, words can be numerals; we could as easily express the same numbers by using the numerals "one, two, three, four, five, ...". In the hexadecimal numeral system, used with computers, the symbols from "A" to "F" are numerals for the decimal values 10 through 15. More exotic ways to represent numbers include Church numerals.
