answers: the result
context: coproduct operation, and general coproducts are perhaps the most abstract of all the generalizations of addition. Some coproducts, such as "Direct sum" and "Wedge sum", are named to evoke their connection with addition. Addition, along with subtraction, multiplication and division, is considered one of the basic operations and is used in elementary arithmetic. Subtraction can be thought of as a kind of addition—that is, the addition of an additive inverse. Subtraction is itself a sort of inverse to addition, in that adding and subtracting are inverse functions. Given a set with an addition operation, one cannot always define a corresponding </s> an infix operator and therefore a binary operator, complicating the notation of an empty product. Some programming languages handle this by implementing variadic functions. For example, the fully parenthesized prefix notation of Lisp languages gives rise to a natural notation for nullary functions: Empty product In mathematics, an empty product, or nullary product, is the result of multiplying no factors. It is by convention equal to the multiplicative identity (assuming there is an identity for the multiplication operation in question), just as the empty sum—the result of adding no numbers—is by convention zero, or the additive identity. The term "empty </s> the squaring operation only produces non-negative numbers; the codomain is the set of real numbers, but the range is the non-negative numbers. Operations can involve dissimilar objects. A vector can be multiplied by a scalar to form another vector. And the inner product operation on two vectors produces a scalar. An operation may or may not have certain properties, for example it may be associative, commutative, anticommutative, idempotent, and so on. The values combined are called "operands", "arguments", or "inputs", and the value produced is called the "value", "result", or "output". Operations can have fewer or more than two inputs.
