The ⊇ symbol, formally known as "Superset Of," is a fundamental mathematical operator used in set theory. It indicates that a given set contains all the elements of another set, and may even be exactly equal to it. While rarely seen in casual texting, this symbol frequently appears in academic papers, logic equations, and technical documentation to define precise relationships between different groups of data.
