As a number, zero means nothing —an absence of other values. It plays a central role in mathematics as the identity element of the integers, real numbers, and many other algebraic structures. As a digit, zero is used as a placeholder in place value systems. Historically, it was the last digit to come into use.
Common names for the number 0 in English include zero, nought, naught (/ nɔːt /), and nil. In contexts where at least one adjacent digit distinguishes it from the letter O, the number is sometimes pronounced as oh or o (/ oʊ /). Informal or slang terms for 0 include zilch and zip.
