Key Concepts

Set

A set is a collection of distinct objects considered as an entity in mathematics. Sets serve as the foundational building blocks in set theory, where elements are grouped together based on shared properties.

Subset

A subset is a set in which every element is also contained in another set. The notation A ? B means that every element of set A is also an element of set B, which is a fundamental concept in set theory.

Reflexivity of the Subset Relation

The reflexivity of the subset relation states that every set is a subset of itself. This foundational property means that for any set A, the statement A ? A is always true, ensuring logical consistency in set theory.
