More specifically, a binary operation on a set is a binary operation whose two domains and the codomain are the same set. However, a binary operation may also involve several sets. For example, scalar multiplication of vector spaces takes a scalar and a vector to produce a vector, and scalar product takes two vectors to produce a scalar. Sometimes, especially in computer science, the term is used for any binary function. This is a different binary operation than the previous one since the sets are different. Many also have identity elements and inverse elements. The first three examples above are commutative and all of the above examples are associative.
Powers are usually also written without operator, but with the second argument as superscript. They are also called, respectively, Polish notation and reverse Polish notation. S for all a and b in S. An example of an external binary operation is scalar multiplication in linear algebra. Here K is a field and S is a vector space over that field. S to K, where K is a field and S is a vector space over K. It depends on authors whether it is considered as a binary operation.
