Combined Filters VZero Front Sums The VZero Front Sums (VTZ-FS) is a so called "combined filter", a combination of two filters:
VZero (VTZ) is a different representation of the VTracs (VTX) concept with the difference that the digits start with 0 rather than 1. That simplifies the conversion drastically as the first five digits (0, 1, 2, 3 and 4) are the same in both number and VZero conversion. The Front Sums filter is a so called "math filter". Math filters are created through calculations. You get the sum of a number by adding up the digits within that number. The is the first digit of that sum. If the sum is only one digit the Front Sums filter returns 0. To show you how to calculate the VZero Front Sums filter select one of the links below for a step by step example.
