Produktoperasjonen, in mathematics often referred to simply as the product operation, is a binary operation that combines two elements to produce a third. It is usually denoted by symbols such as juxtaposition (ab), a dot (a · b), or a times sign (a × b). Formally, it is a function from a set S × S to S: (a, b) ↦ a · b.
In algebraic structures, the product operation is defined on a set with a rule that specifies how
Different contexts use different flavors of product. Internal product refers to multiplying elements within a single
