Questions tagged [alignat]

{alignat} is an environment provided by math packages that permits multiple related equations to be aligned at a common reference point, usually a sign of relation, without automatically adding extra horizontal space between components. For general questions about aligning document elements, use {horizontal-alignment} or {vertical-alignment} instead.
