Cardinality Elements Set

AI Thread Summary

Cardinality of a set refers to the number of elements within that set, defining its size. While this concept applies straightforwardly to finite sets, it becomes more complex when discussing infinite sets. The discussion emphasizes that cardinality is not just a reference to quantity but represents that specific number. Understanding cardinality is essential for distinguishing between different types of infinite sets. Overall, cardinality serves as a fundamental concept in set theory.
