| 11) In the game of golf, the score is determined by how many strokes under par the player can achieve for each hole on the course. A score of Par is zero (0) and means that the player achieved putting the ball in the hole in the desired number of strokes. If a player puts the ball in the whole in less than the number of desired strokes, then his score is “under Par” and can be considered a negative number. If after four holes, Allen’s score is “3 under par”, which number could represent his score? |
