Polynomial Expressions and Horner's Method

Some expressions, such as polynomials, use the same variable several times for their
solution. For example, the expression
4 3 2
Ax + Bx + Cx + Dx + E
uses the variable x four different times. A program to calculate such an expression
using RPN operations could repeatedly recall a stored copy of x from a variable.
Example:
4 3
Write a program using RPN operations for 5x + 2x , then evaluate it for x = 7.
