... means that n=m. If f (n) is positive, then (n 1) / 2 (m 1) / 2 , and multiplying both sides by 2 and subtracting 1 means that m=n. So f is 1-1. To show onto: Let x be any integer (WTS: there is a natural number n that gets mapped to x) If x is negative, then define n such that n / 2 x , so ...

... Solution: If we first color all the panes yellow and then color the remaining 3 panes white (to represent unpainted) we can solve an easier problem. The solution has to be mirror symmetric, if we reflect along the vertical middle line. In the central column there could be either 3 or 1 white panes. ...
