Names for the number 0 in English the first recorded usage of the word "love" to mean "no score" is by Hoyle in 1742 (OED, 2nd Edition). BBC Radio 5 Live has broadcast spin-off versions of its football phone-in 6-0-6 (""six-oh-six"") focused on cricket and tennis, branded as "6-Duck-6" and "6-Love-6" respectively, in the summer months during the soccer off-season. Another name for 0 that is used in sports is "nil". This is derived from the Latin word "nihil", which means "nothing". Although common in British English, in football results and the like, it is only used infrequently in U.S. English. The British "nil" is not slang,
Zero of a function generally used when there are infinitely many zeros, and they have some non-trivial topological properties. For example, a level set of a function formula_1 is the zero set of formula_26. The cozero set of formula_1 is the complement of the zero set of formula_1 (i.e., the subset of formula_23 on which formula_1 is nonzero). In algebraic geometry, the first definition of an algebraic variety is through zero sets. Specifically, an affine algebraic set is the intersection of the zero sets of several polynomials in a polynomial ring formula_31 over a field. In this context, a zero set is sometimes called
