# Definition:Multiplication/Product

## Definition

Let $a \times b$ denote the operation of multiplication on two objects $a$ and $b$.

Then the result $a \times b$ is referred to as the product of $a$ and $b$.

Note that the nature of $a$ and $b$ has deliberately been left unspecified.

They could be, for example, numbers, matrices or more complex expressions constructed from such elements.
