Cards render mathematics with KaTeX. Use Edit source in the card editor to write equations.
| You write | You get |
|---|---|
$x^2$ or \(x^2\) |
Inline math |
$$\frac{a}{b}$$ or \[\frac{a}{b}\] |
A display equation on its own line |
$\ce{H2O}$ |
Chemistry, inside math delimiters |
Code spans and code blocks stay literal, so you can show LaTeX source without rendering it. If a command isn’t supported, Armin keeps its source and shows a warning in the preview.
