In mathematics, an inverse function is a function that "reverses" another function. So, for example, (2, -90) would be (-2, 90). By the way, nice MacBook Air, Rian Dennis.
to make it simpler, pretend you start from 1. 1,7,so on. multiply six by 79, to get 474. but because you are starting from 5 and not 1, you have to add 5 on.
