Functions

Functions are specific methods that can be applied to produce a standard result.

In mathamatics it is a routine which expresses a method that can be followed in order to manipulate values. An example of a function may be "n*2" this indicates that the variable "n" must be multiplied "*" by the value "2". Also if "n=6" which means the variable "n" should be taken as the equivalent of the value "6" and could be substituted as such. If these two functions are combined the result is "6*2" and the result of this would be "12".
