The term "2-3" can refer to a variety of concepts depending on the context. In mathematics, it simply represents the numbers two and three, which are consecutive integers. It can also denote a range or a grouping, such as in sports or games where teams or players might be categorized into groups of two to three. In a different context, "2-3" might refer to a specific strategy or formation, such as in basketball, where a team might use a 2-3 zone defense.
