What type of mathematical genius? Are you looking at 4 or more standard deviations above the mean? There are differing areas of mathematics...statistics, quantum mechanics, differential equations, calculus, trigonometry, geometry, algebra, etc. Does the math genius need to know that i equals the square root of -1? Gaming aspects could incorporate the Pythagorean Theorem. I have taught Business Math and some of the minor mathematics; I have also tutored MBA and other college level students. On business side, I was a district manager for for financial analysis company. What type of math genius are you looking for? BTW, I am anti-common core, the destroyer of teaching student mathematics properly.
