For the Bart and Sam question, Bart had 123 - 180 or -57 points. Sam had 185 - 255 or -70 points, so Bart won the game by 13 points. The other question about the integers will work with any two numbers where one is 8 larger than the other. Take the smaller number and make it negative. Two such number pairs would be 9 and -1 or 29 and -20.
