In economics, there is something called elasticity.
Elasticity is simply an inverse slope.
If a graph of elasticity is a horizontal line, it is referred to as infinitely elastic. Situations Hi Jonathan, Nowhere is it written in stone what mathematical objects should be studied. Obviously, objects that are interesting and useful have received the most attention. Believe me, it would be a real pain to try to do algebra without the associative law. It just means that whatever actual number you name, it eventually gets bigger than that.
