When to use Align Environment
Aligns multiple displayed equation rows at chosen alignment points. In source, start from the exact align command instead of imitating the rendered glyph with Unicode characters or manual spacing. This keeps the expression editable and gives the renderer enough structure to apply mathematical spacing correctly.
Syntax
alignThe documented syntax belongs to amsmath. Keep every required argument, brace pair, and environment boundary intact when moving the command between an editor, Markdown processor, notebook, or publishing system.
Example
\begin{align}a&=b\\c&=d\end{align}Rendered output

Copy and compatibility checks
- Copy
alignexactly; changing its case or removing a leading backslash can turn it into plain text. - Confirm that the destination loads amsmath before relying on this command.
- Render the example once, then inspect grouping, limits, scripts, and spacing before publishing.
