AI overview

A union is a mathematical operation (shown by the symbol "∪") that combines two sets into a single set containing all the distinct elements from both. It matters because it's a fundamental tool for organizing and comparing groups of items in mathematics, logic, and computer science.

数学において集合族の和集合（わしゅうごう）、あるいは合併集合（がっぺいしゅうごう）、合併（がっぺい、英語: union）、あるいは演算的に集合の和（わ、英語: sum）、もしくは結び（むすび、英語: join）とは、集合の集まり（集合族）に対して、それらの集合のいずれか少なくとも一つに含まれているような要素を全て集めることにより得られる集合のことである。
