Second derivative I think. Inflation is change in prices. Change in inflation is a second order derivative? I wish more Americans knew at least a little conceptually about derivatives. Personally, I need to review them. Anecdotally, the number of accountants that I've met that haven't progressed beyond middle school level math is depressing as well.
