 Monomy: Algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
 For example:
 ax^2
 It is a monomial.
 In this case we have the following expression:
 18x
 Using the given definition, we have that the expression is a monomial.
 
 A .. monomial

Maybe fx = lxl because of the way the x is positioned is that what he
