Equation Editor FAQ
How do I insert fractions and square roots?▼
In the palette above the editor, select the "Fractions & Roots" tab and click "a/b" for \frac{a}{b} or "√x" for \sqrt{x}. Replace the placeholder variables with your values.
Can I paste MathML into Microsoft Word?▼
Yes! Click "Copy MathML" in the editor. Open Microsoft Word, press Ctrl+V (or Cmd+V on Mac), and Word will automatically format the equation into native editable Word Equation format.
Does this editor support multi-line equations?▼

How do I use these equations in Notion or Obsidian?▼
Click "Copy Markdown" in the editor, then paste the $$ ... $$ block straight into Notion or Obsidian. Both render it as a live math equation with no extra steps.
Does this work with Google Docs?▼
Yes. Click "Copy MathML" and paste into Google Docs to get a native editable equation. For slides, download a transparent PNG or vector SVG instead.
