- 0 (zero ; BrE: or AmE: ) is both a number  and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems. In the English language, 0 may be called zero, nought or (US) naught, nil, or — in contexts where at least one adjacent digit distinguishes it from the letter "O" — oh or o. Informal or slang terms for zero include zilch and zip. Ought or aught () has also been used historically.
