This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $$ ... $$ 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*}.
  • Mico's (earlier posted) answer ( tex.stackexchange.com/a/40531/78134 ) to a related question is a little more detailed, and -- importantly -- suggests that this answer here might even be wrong in some important ways (not least that $$ $$ does not give a numbered equation) – owjburnham Dec 28 '18 at 11:01
