The scoring system works as follows, it is the same for singles and doubles so where player is used take it to also mean the team in a doubles match:
Love* (being zero) then 15 , 30, 40 and if the player on 40 scores the next point they win the game. If both players have 40, then deuce is called and a player has to score two points in succession to win. At deuce they play for the advantage, if somebody scores a point they get the advantage, then, after scoring another point straight away, they win that game. If, while one player has an advantage, the other player scores a point, it goes back to deuce.
So the answer to your question "What comes after 30 love?" (which means one person has scored two points while the other has yet to score) could be followed by the person with 30 scoring another point in which case it is 40 love or the other person scoring their first point which makes it 30 15.

The word comes from the French phrase deux, which means "at two" (as in needing two more points to win). Also, there is a Latin prefix in it (du) which mean two; twice.
The tennis points go like this: Love (0 points) 15 (1 point) 30 (2 points) 40 (3 points) Game (4 points) That is just how tennis is played.

You would hear those words in tennis. They are for keeping score in a game. The game points go from love (0) to 15, 30, 40 and then game. If it is 40 all, it is deuce. To win a deuce, you must win by 2 points. It goes from deuce to the advantage of the player who won that point, and then game.
