I work for a company that touts that there are over 250,000 possible ways to dress their hamburger. We offer 15 condiments. As far as I can remember from high school math, that is a "function" of 15 (15!). To find all possible combinations of condiments would require an equation of 15x14x13x12x11... all the way to 1. This results in over 3 trillion possible combinations. Am I wrong or is my company seriously underselling it's potential?
