Logical NNOR

☞ This page belongs to resource collections on Logic and Inquiry.

The logical NNOR (“Neither Nor”) is an operation on two logical values, typically the values of two propositions, that produces a value of true if and only if both of its operands are false. In other words, it produces a value of false if and only if at least one of its operands is true.

The truth table of $p ~\operatorname{NNOR}~ q,$ also written $p \curlywedge q,\!$ appears below:

$\text{Logical NNOR}\!$
