How do they start scoring in Tennis and Badminton?

Answer 1

Tennis and Badminton are actually very different. They don't score the same way.

In tennis, it starts with love, 15, 30, 45, deuce or game. You always say your score first, then the opponent's. Love love, fifteen love, thirty love, fourty-five love. Deuce. Add in, add out. Deuce in when both sides have fourty-five (three points) If you play with add (or advantage) then you have to win two more points after reaching deuce. If you don't play with add, then after reaching deuce, you only have to win one more point.

In badminton, you play to 21, and you score with normal scoring. 0,0 you would start with, whoever gets the point has a new score of 1. Much less weird :)
