How do you keep score in tennis and why is it dome that way?
In tennis, the scoring system is unique and somewhat complex. Points progress from love (zero), to 15, 30, and 40, and a game is won by the first player to reach 40 with a two-point lead. This unusual system is thought to have originated from the face of a clock, with quarter-hour increments. The reason for the two-point lead rule is to provide a clear winner, avoiding any chance of a tie. It's a system that keeps matches exciting, as there's always a chance for a player to make a comeback.
