     These procedures are for creating and performing operations on single-
 variable polynomials (like ax^2 + bx + c).

     poly (c1, e1, c2, e2, ...)  - creates a polynomial from the parameters
                                   given as coefficient-exponent pairs:
                                   c1x^e1 + c2x^e2 + ...
     is_zero (n)                 - determines if n = 0
     is_zero_poly (p)            - determines if a given polynomial is 0x^0
     poly_add (p1, p2)           - returns the sum of two polynomials
     poly_sub (p1, p2)           - returns the difference of p1 - p2
     poly_mul (p1, p2)           - returns the product of two polynomials
     poly_eval (p, x)            - finds the value of polynomial p when
                                   evaluated at the given x.
     term2string (c, e)          - converts one coefficient-exponent pair
                                   into a string.
     poly_string (p)             - returns the string representation of an
                                   entire polynomial.
