In mathematics , an operation is a calculation from zero or more input values -LRB- called operands -RRB- to an output value .. mathematics. mathematics. The number of operands is the arity of the operation .. arity. arity. The most commonly studied operations are binary operations of arity 2 , such as addition and multiplication , and unary operations of arity 1 , such as additive inverse and multiplicative inverse .. arity. arity. addition. addition. multiplication. multiplication. additive inverse. additive inverse. multiplicative inverse. multiplicative inverse. An operation of arity zero , or 0-ary operation is a constant .. arity. arity. 0-ary operation. 0-ary function. constant. constant ( mathematics ). The mixed product is an example of an operation of arity 3 , or ternary operation .. arity. arity. mixed product. mixed product. ternary operation. ternary operation. Generally , the arity is supposed to be finite , but infinitary operations are sometimes considered .. arity. arity. In this context , the usual operations , of finite arity are also called finitary operations .. arity. arity
