Why does tennis score 1 to 15, score 2 to 30 and score 3 to 40?

First, it has a lot to do with the origin of tennis. Tennis was mainly developed in France and Louis Dynasty. At that time, it was decided according to the convenient materials at the time of integration. At that time, it was scored with a very simple fluctuating clock, so every time you get a point, you have to turn the clock 1/4. If you get two points, that's 30, based on this base.

Second, because the most primitive tennis originated from the court, the scoring method can be understood on the spot. They use a dial clock to score points. Every time they score a goal, the clock turns for a quarter of an hour, that is, 15 minutes. Similarly, the clock was set to 30 o'clock in two minutes. Everything is based on their convenience. This is the origin of 15 and 30.

Third, as for 40 points, it is strange that it is not a multiple of 15. This is because in English, the "fifteen" in 15 minutes is disyllabic, and the "thirty" in 30 minutes is also disyllabic. But by 45, the English pronunciation was "45", which became three syllables. At that time, the British felt a little hasty and did not conform to the principle of "convenience".

Fourth, so they changed it to 40 points of the same two syllables. This is the origin of the seemingly illogical 40 points. Although this scoring method seems a bit strange, it still follows the tradition. After all, everyone is used to this scoring method, so everyone is used to it and familiar with it, and it has been used until today.

In fact, some of the rules and methods we usually use have been slowly continuing from the beginning. People are already very familiar with these methods and will not change them at will.
