Answer 1

   It looks like an algebraic equation/formula to me ... it's most likely used in accounting or some sort of business math. "P" may stand for principal or profit, but I don't know what "S" stands for and I don't recognize the equation.

Where did you see this equation?

I hope I helped some ...
