Reversed Double Stroke Not Sign Symbol
⫭ is the reversed double stroke not sign (U+2AED), used as a math/logic symbol in specialized notation.
U+2AED
⫭ (U+2AED) is a mathematical symbol with a specific “not” style meaning. It’s mainly used in technical contexts where authors need a symbol that clearly indicates negation or exclusion. Use it carefully and verify compatibility in your target fonts and platforms.
Reversed Double Stroke Not Sign Symbol Meaning
⫭ is named “Reversed Double Stroke Not Sign” and is encoded at U+2AED. In mathematical and logic notation, a “not sign” indicates negation—often meaning “not,” “does not hold,” or “excluding a condition,” depending on the surrounding formula. The “reversed double stroke” design distinguishes it from other negation symbols, which may look similar but represent different operators in particular standards or sets of notation. Like many Unicode math symbols, its meaning is determined by the context in which it appears (for example, within a larger logical expression or definition).
Common uses
- •Negating a predicate in specialized mathematical or logic expressions
- •Marking “does not satisfy” conditions in formal problem statements
- •Labeling excluded states or constraints in technical documents
- •Creating consistent notation for logic-heavy diagrams and papers
- •Displaying the exact Unicode character in math-focused writing and datasets
Examples
⫭ Reversed Double Stroke Not Sign
- ⫭Let P be true; ⫭P means P does not hold.
- ⫭If ⫭Q, then the condition is excluded from consideration.
- ⫭Define R as the set of values where ⫭(x ∈ A).
- ⫭We require ⫭(f(x) = 0) for all x in the domain.
- ⫭The proof assumes ⫭S to derive a contradiction.
