If this operation is applied to a function and the derivative of another function, the result can be integrated by parts.
When this operation is applied to two quaternions [kwa-TEHR-nee-ons], it is anticommutative. If this operation is applied to a function and the derivative of another function, the result can be integrated by parts. For matrices [MAY-trih-ses], this operation pairs each of the rows of the first matrix with each of the columns of the second matrix. When this is applied to two prime numbers, the result is composite. Name this operation that can be done repeatedly using exponents and which can represent repeated addition.
