Why does tennis scoring go to 40 instead of 45?

Answer 1

Tennis scoring goes to 40 instead of 45 because of the historical origins of the game. The scoring system in tennis dates back to the 16th century in France, where the word "quarante" (meaning forty) was used to represent the number 40 in the scoring system. Over time, the scoring system evolved to its current form, where players need to win four points to win a game, with the scores progressing from 15 to 30 to 40. The use of 45 in scoring is not necessary as the game can be won at 40.
