multiplication

n. act or state of being multiplied; (Mathematics) basic mathematical operation in which one quantity is multiplied by another (i.e. 4 x 2 = 8); increase in quantity; reproduction, procreation

Multiplication is the mathematical operation of adding together multiple copies of the same number. For example, four multiplied by three is twelve, since three sets of four make twelve:Multiplication can also be viewed as counting objects arranged in a rectangle, or finding the area of rectangle whose sides have given lengths.Multiplication is one of four main operations in elementary arithmetic, and most people learn basic multiplication algorithms in elementary school. The inverse of multiplication is division.
