U+2A41 "⩁" Union with Minus Sign Unicode Character

Unicode Version 17.0

U+2A41 "⩁" Union with Minus Sign is a mathematical symbol used in set theory and algebra to denote a union operation that also incorporates a subtraction or exclusion of certain elements. It represents a combination of two concepts: the union of sets, typically symbolized by the cup-like shape, and a minus sign, indicating that while sets are combined, some part is removed or differentiated. This symbol is less common than the standard union or minus signs, but it appears in specialized mathematical contexts where the union of sets needs to explicitly account for the removal of a subset. Its inclusion in Unicode ensures that mathematicians and logicians can encode this precise operation in digital text without resorting to makeshift combinations of other characters.
