In mathematics, "doubles" refer to the concept of multiplying a number by two. For example, if you have the number 3, its double is 6 because 3 times 2 equals 6. This idea is often used in everyday situations, like when sharing snacks or dividing items evenly among friends. In games, "doubles" can also mean playing in pairs, such as in tennis or badminton. In these sports, two players team up against another pair, making the game more social and fun. Doubles can enhance teamwork and strategy, as players must communicate and coordinate their movements effectively.
