Abstract—Difference equations are discrete analogy of the
differential equations. These equations appear in mathematical
modeling of physics and engineering problems, economic and
population subjects that deal with discrete data and variables.
In this article, we will consider and solve these types of
equations that are non-homogeneous. The solving method is
performed using by multiplicative discrete differential equations.
The importance of this method is that by using the concept
of discrete derivative, the analytical method and analytical solutions are given to linear and non -linear difference equations.
