This category contains results about the negation operator of propositional logic.

Definitions specific to this category can be found in Definitions/Negation.

The **logical not** or **negation** operator is a unary connective whose action is to reverse the truth value of the statement on which it operates.

- $\neg p$ is defined as:
**$p$ is not true**, or**It is not the case that $p$ is true**.

Thus the statement $\neg p$ is called the **negation** of $p$.

$\neg p$ is voiced **not $p$**.
