How to make a newline in equation in remnote?

Need to edit long equation inremnote and need newline. But \ does not work.
I tried method here, but neither of them works.
Anyone give me a hand? Thanks.

For a simple newline use \\ (the latex popup may cover the newline’s contents until you click away) .
For aligned wrap with \begin{aligned} \end{aligned} and & to mark alignment points
RemNote uses KaTeX, here’s the full reference.

Thanks for your sharing. It really helps. :grinning:
