⩆ denotes a union relationship placed above an intersection in mathematical notation.
U+2A46
The symbol ⩆ is known as the union above intersection. It’s a compact math operator used when you want to display a union-like structure over an intersection. Below you’ll find practical ways to copy and use it in documents and code.
Union Above Intersection Symbol Meaning
⩆ (UNION ABOVE INTERSECTION, U+2A46) is a mathematical symbol that combines the ideas of union and intersection by placing the union “above” the intersection. Visually, it’s designed for stacked operator notation, where one operation is presented over another to clarify structure in formulas. In practice, you may see it in typed math expressions to indicate how sets or logical conditions relate when arranged in a vertical, operator-stacking style. When writing or formatting math, it can help convey hierarchy or grouping without relying on extra parentheses.
Common uses
- •Writing set or logic expressions where you want a union operation stacked above an intersection
- •Labeling or typesetting mathematical constraints in notes, slides, or textbooks
- •Creating clearer, vertically structured formulas in word processors that support Unicode math symbols
- •Adding custom operator notation in math markup or equations when a stacked symbol is preferred
- •Designing educational or documentation graphics that show set relationships
