There are many different kinds of products in linear algebra. Some of these have confusingly similar names (outer product, exterior product) with very different meanings, while others have very different names (outer product, tensor product, Kronecker product) and yet convey essentially the same idea. A brief overview of these is given in the following sections. By the very definition of a vector space, one can form the product of any scalar with any vector, giving a map $${\displaystyle \mathbb {R} \times V\rightarrow V}$$.
