Logical conjunction

&#9758; This page belongs to resource collections on Logic and Inquiry.

Logical conjunction 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 true.

The truth table of p AND q (also written as p &and; q, p & q, or p$$\cdot$$q) is as follows:
