The term 'Numbers on a Golf Course' refers to the score that a golfer achieves on each hole. Pars are the number of strokes that a skilled golfer should require to complete a hole. A par is typically between three and five strokes, depending on the length of the hole. A golfer's score is compared to the par for each hole, with a score below par being referred to as a 'BIRDIE' and a score above par being referred to as a 'BOGEY'.
