Note: Don't forget the dot at the end of the line.
The user available predicates are: 1) poly2list/2 2) simpoly_list/2 3) simpoly/2 4) scalepoly/3 5) addpoly/3
poly2list/2 - transforms a list representing a polynomial (second argument)
into a polynomial represented as an expression (first argument)
simpolylist/2 - simplifies a polynomial represented as a list into
another polynomial as a list.
simpoly/2 - simplifies a polynomial represented as an expression
as another polynomial as an expression.
scalepoly/3 - multiplies a polynomial represented as an expression by a scalar
resulting in a second polynomial. The two first arguments are assumed to
be ground. The polynomial resulting from the sum is in simplified form.
addpoly/3 - adds two polynomials as expressions resulting in a
third one. The two first arguments are assumed to be ground.
The polynomial resulting from the sum is in simplified form.
foo/Nmeans the funciton
Nparameters (this is known as arity). These names are the ones requested in the assignment.
