In mathematics, multiplication is a binary operation between two elements in a set, in a broad sense. Depending on what set of elements are interacting, there are many types of multiplications with different properties. The multiplication sign is represented by the "x" (
) or a medium-sized dot 
. Multiplication is the inverse of division.
Multiplication is achieved by adding a number to itself as many times as the second number has value. For example, 
would equal 
, which in turn equals 
. This is called repeated addition.
Types of Multiplications
