After tennis was introduced to Britain, the British heard that the French used the pronunciation of I'oeuf (Loew) to represent zero, so they looked for words close to the pronunciation of I'oeuf in their vocabulary, and later used Love to represent zero.

Taking 15 as the calculation unit was once a mystery. The three numbers 15, 30 and 40 are by no means randomly selected by people. After research, a man named Qin Gosling thought that these three numbers must be the units of measurement that those tennis players were familiar with or used at that time, and they were based on the astronomical sextant. The sextant is set at 1/.
At that time, tennis scored 4 points per game, 4 15 points per degree. Just as four 15 degrees form 1/6 circles, the gains and losses of each point are calculated with 15 as the base. As for 45, it was changed to 40 for the convenience of grading pronunciation. In early tennis, there were 4 games in each game, with 4 points in each game.
