Symbols:General/Identity

Identity

$\equiv$

The symbol $\equiv$ can be used to distinguish an identity from a conditional equation, but frequently (and usually on $\mathsf{Pr} \infty \mathsf{fWiki}$) the equals sign $=$ is used instead.

The $\LaTeX$ code for \(\equiv\) is \equiv .

The $\LaTeX$ code for \(\not \equiv\) is \not \equiv .
