What come in sets for math?

In mathematics, sets are collections of distinct objects, typically used to group numbers or elements that share a common property. Sets can be finite or infinite and are often denoted using curly braces, such as {1, 2, 3} or {x | x > 0}. Common examples include sets of numbers, such as natural numbers, integers, or rational numbers, as well as sets used in functions and relations. Understanding sets is fundamental for various branches of mathematics, including algebra, calculus, and statistics.
