  • $$ ... $$ is a delimiter for a numbered display equation. It should no longer be used. The recommended equivalent for this is begin{equation} ... \end{equation}.
  • \[ ... \] is a delimiter for a non-numbered display equation. It is the short version of the begin{equation*} ... \end{equation*}.
