Five times eighty one minus nine, let's figure out what five times eighty one is, so eighty one times five, one times five is five, eight times five is forty, so this right over here is four hundred and five, so it becomes four hundred and five minus nine, so that is going to be equal to if we are subtracting ten it would be 395, but we're subtracting one less than that so it's 396, and we're done.
