Mathematical infinity refers to a concept that describes something without any limit or end. It is often represented by the symbol ∞ and is used in various branches of mathematics, such as calculus and set theory. Infinity can represent an unbounded quantity, like the number of points on a line or the size of a set, such as the set of all natural numbers 1, 2, 3, .... In mathematics, there are different types of infinity. For example, Georg Cantor introduced the idea of countable and uncountable infinities, distinguishing between sets that can be matched with natural numbers and those that cannot. This exploration of infinity helps mathematicians understand and work with concepts that extend beyond finite limits.
