Logical NOR

Binary operation that is true if and only if both operands are false

In Boolean logic, logical NOR, non-disjunction, or joint denial is a truth-functional operator which produces a result that is the negation of logical or. That is, a sentence of the form (p NOR q) is true precisely when neither p nor q is true—i.e. when both p and q are false. It is logically equivalent to and , where the symbol signifies logical negation, signifies OR, and signifies AND.
