### Extension to Horner's rule

Horner's rule is used in computation to calculate polynomials using reduced multiplications. Please see the following references

1. Eric W. Weisstein. "Horner's Rule." From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/HornersRule.html
2. http://planetmath.org/encyclopedia/HornersRule.html
The same rule can be extended and used for debugging. When you have "n" unknowns in debugging, your problem is a polynominal of degree "n". Solve the unknowns 1 by 1 as Horner's rule does for calculation of polynomials, by taking factors and converting the calculation to n multiplications and additions. Solving too many unknowns at once is complex, solve them one by one
