Copy it into Word as a real equation, save a PNG, or download a .tex file.
Questions
Can I paste the equation into Word?
Yes. “Copy for Word” copies it as a real Word equation you can still edit. It also works in OneNote.
Do I need to know LaTeX?
No. The symbol buttons insert the LaTeX for you, and there's a cheat sheet on the page.
Can I write chemistry equations?
Yes. Use \ce{...}, for example \ce{2H2 + O2 -> 2H2O}.
Can I work on it with others?
Yes. Start a live room and send the link to edit the equations together.
