# LISP Polynomial Calculator

* A simple polynomial calculator in lisp

* Polynomials are in the form 
    '(((SYMBOL EXPONENT) MULTIPLIER) ((SYMBOL EXPONENT) MULTIPLIER))

* For example this:
    '(((x 2) 5) ((((x y) (2 3)) 5))) = 5x^2 + 5x^2y^3

* The functions that exist are poly+ poly- poly*

Below you can see an example of the test output:
