[PDF] A Note on Horners Method - Illinois Wesleyan University

As a division algorithm, Horner's method is a nesting technique requiring only n multiplications and n additions to evaluate an arbitrary nth-degree polynomial, which can be surveyed by Horner's theorem (see, for example, [1]) Q(x) = bdxd-1 + bd-1xd-2 + ··· + b2x + b1
