RE: Multiply Function [x]
You can think of any number (even with decimals) as a polynomial of digits. Each digit is multiplied by a power of 10. For example, the number 123.4 is a polynomial ranging from 10 to the power 2 to 10 to the power -1. The digits of the number are the coefficients of the polynomial:

N(2,-1) = 1 * 10^2 + 2 * 10^1 + 3 * 10^0 + 4 * 10^(-1)

So you can multiply two numbers by multiplying the polynomials that represent them.
