The other rules of vector manipulation are subtraction, multiplication by a scalar, scalar multiplication also known as the dot product or inner product , vector multiplication also known as the cross product , and differentiation. There is no operation that corresponds to dividing by a vector.

See vector analysis for a description of all of these rules. Although vectors are mathematically simple and extremely useful in discussing physics, they were not developed in their modern form until late in the 19th century, when Josiah Willard Gibbs and Oliver Heaviside of the United States and England, respectively each applied vector analysis in order to help express the new laws of electromagnetism, proposed by James Clerk Maxwell.
