Number
== Meaning ==
Zero is 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. Names for the number 0 in English include zero, nought (UK), naught (US; /nɔːt/), nil, or—in contexts where at least one adjacent digit distinguishes it from the letter O—oh or o (/oʊ/). Informal or slang terms for zero include zilch and zip. Ought and aught (/ɔːt/), as well as cipher, have also been used historically.
