Numerals, or number names, are adjectives or nouns used in a language to represent numbers. They may be based on different ways of counting (decimal, vigesimal, and so on), but are a linguistic concept, rather than a mathematical one, and should therefore be distinguished from numeral systems in the mathematical sense. There is nevertheless some overlap between the concepts of numeral and numeral system, especially in ancient languages — in which mathematical notation and ordinary language were not always distinguished.
