Statistics on much complicated math is used in real life?

Hi! i need help on a essay in which i argue that complicated math i.e. algebra, geometry, calculus is useful in real life, i need a statistic of some sort or a quote of a famous guy to defend my argument
(it would be nice if it was a statistic talking about how much people really use *hard* math.)
♥THANK YOU♥
