The Union symbol (∪) is a fundamental mathematical operator used in set theory to denote the combination of two or more sets. It represents a new collection containing all distinct elements present in the original sets, conceptually similar to the logical 'OR' operation. Outside of strict mathematics, it occasionally appears in technical documentation or logic diagrams to symbolize the merging of different groups.

In Programming
In programming and academic writing, this symbol is frequently used in LaTeX (\cup) for rendering math formulas. While rarely typed directly in source code, logical equivalents like the | operator or .union() methods serve the same function in languages like Python.
