A method of financial management that involves rounding any transaction up to the next dollar amount. Bank math prevents any overdrafting of bank accounts because the amount remaining in the account is always more than you believe it to be.
Let's see, the burger is $4.79, and the fries are $2.19. So quick Bank Math, that's like $8, and I have $15 in my account, so I should have $7 left for tonight.
