Math on iOS?

Just purchased Scrivener for my iPad Pro, and have quickly gone through the tutorial.

My only question is this: how do I insert inline or displayed mathematics? I have several LaTex apps on my iPad, including TexWriter—which is also a great app. Any way of generating equations using it and pasting them into Scrivener?

The LaTeX code itself is just text, which you can paste wherever you want. But iOS Scriv has no ability to render it as a nicely formatted equation. For that, your best approach is likely to be compiling to MultiMarkdown using desktop Scrivener.
