“0, 0, 0,”™ is the watchword for balance or harmony. Each 0 represents a vectorial deviation of a given variable from an ideally balanced coordinate along some axis. The idea may be generalized to n-dimensions by simply adding zeroes, such as “0, 0, 0, 0” for a four variable function, but generally for really complex functions, useful composite functions are defined that are themselves functions of two or more variables. In this way, the vectorial representation of deviations from the ideal values can still be done graphically in three dimensions. For more, see my book Maximum Irony.
