The document summarizes scoring systems for tennis and badminton. In tennis, scores from 0 to 3 points are called "love," "15," "30," and "40." If it is 40-40, the score is called "deuce." In badminton, matches are played in a best of 3 sets, with each set played to 21 points. The document provides examples of filling out a scoresheet to track the score of matches in these sports.
