N-ary Union Operator With Plus Symbol
⨄ is the n-ary union operator with a plus, used to denote a union-style combination in mathematical notation.
U+2A04
The symbol ⨄ is named the N-ary Union Operator with Plus. It’s a specialized math character used in formal writing where union-like operations appear in combined forms. Use it for copy/paste needs or when matching Unicode math notation.
N-ary Union Operator With Plus Symbol Meaning
⨄ (Unicode U+2A04) is the “N-ary Union Operator with Plus.” In mathematical typography, “n-ary” indicates the operator can take multiple arguments (more than two) in a single expression. The “with plus” part signals a union operation that is paired with a plus-like combination, often in contexts where results from multiple sets/terms are combined. Because this is a Unicode math operator, it’s typically used in technical documents, math layouts, and typeset content where consistent symbol semantics matter more than general punctuation or decoration.
Common uses
- •Representing a multi-argument union operation in formal math notes
- •Writing set- or term-combination expressions in technical documents
- •Labeling or typesetting expressions in textbooks and lecture slides
- •Using in math-focused UI text (e.g., equation editors or formula help text)
- •Creating consistent Unicode-based symbols for technical writing workflows
