This function is to invert a number using a mathematical formula, by default in a whole of 100 for percentages with a unit defined size of 1. Example if you call InvertNum(25) the result is 75, and InvertNum(50) is 50. All function I understand require at least 3 lines of code, but it's not so true, regarding running, as to the inheritance reference, so maybe just write it out each time is really just one line, with out the function header footer, so that I may have helped one day explain.
