# Negative Cardinality

A mathematical set property of having less than 0 elements (Just like antimatter in Physics.)

*The invention of negative numbers proved to be useful in mathematics. Set operations, however, do not have the idea of having less than 0 elements. We reach the empty set {}, and then stop, but why should we? Imagine a property: subtracting an element that is not in a set creates a potentiality to annihilate such element. Such potentiality could be marked as elements with an apostrophe. I.e., {1,2',2} = {1}.*

*This idea was inspired by "World’s Most Exclusive Club," when thinking about the super-exclusiveness.*

Goals are just assets with negative sign of carnality, so such theory would be useful for formalizing goal pursuit...
