A double negative is a construction occurring when two forms of grammatical negation are used in the same sentence. This is typically used to convey a different shade of meaning from a strictly positive sentence ("You're not unattractive" vs "You're attractive").
In propositional logic, the double negation of a statement states that "it is not the case that the statement is not true". In classical logic, every statement is logically equivalent to its double negation, but this is not true in intuitionistic logic; this can be expressed by the formula A ≡ ~(~A) where the sign ≡ expresses logical equivalence and the sign ~ expresses negation.
Proving a negative or negative proof may refer to: Proving a negative, in the philosophic burden of proof; Evidence of absence in general, such as evidence that there is no milk in a certain bowl; Modus tollens, a logical proof; Proof of impossibility, mathematics; Russell's teapot, an analogy: inability to disprove does not prove
Some problems in machine learning use graph- or hypergraph-based formulations having edges assigned with weights, most commonly positive.A positive weight from one vertex to another can be interpreted in a random walk as a probability of getting from the former vertex to the latter.
A negative answer, commonly expressed with the word no A type of grammatical construction; see affirmative and negative A double negative is a construction occurring when two forms of grammatical negation are used in the same sentence.

Let T N consist of the double-negation translations of the formulas in T. The fundamental soundness theorem (Avigad and Feferman 1998, p. 342; Buss 1998 p. 66) states: If T is a set of axioms and φ is a formula, then T proves φ using classical logic if and only if T N proves φ N using intuitionistic logic.
