☞ This page belongs to resource collections on Logic and Inquiry.
Logical equality is an operation on two logical values, typically the values of two propositions, that produces a value of true if and only if both operands are false or both operands are true.
The truth table of \(p ~\operatorname{EQ}~ q,\) also written \(p = q,\!\) \(p \Leftrightarrow q,\!\) or \(p \equiv q,\!\) appears below:
\(p\!\) | \(q\!\) | \(p = q\!\) |
\(\operatorname{F}\) | \(\operatorname{F}\) | \(\operatorname{T}\) |
\(\operatorname{F}\) | \(\operatorname{T}\) | \(\operatorname{F}\) |
\(\operatorname{T}\) | \(\operatorname{F}\) | \(\operatorname{F}\) |
\(\operatorname{T}\) | \(\operatorname{T}\) | \(\operatorname{T}\) |
