# Multiplying or Dividing Machine

## Description

This machine is used for multiplication, and division purposes. Multiplication is the mathematical operation of scaling one number by another. It is one of the four basic operations in elementary arithmetic. Conceptually, division describes two distinct but related settings. Partitioning involves taking a set of size a and forming b groups that are equal in size. The size of each group formed, c, is the quotient of a and b. Quantitate division involves taking a set of size a and forming groups of size b. The number of groups of this size that can be formed, c, is the quotient of a and b
