title: Use Math in the Editor
description: Add and edit LaTeX math blocks and inline expressions inside the Edvello rich text editor.
---

Edvello’s rich text editor includes built-in math support with KaTeX rendering. You can insert inline expressions, add block equations, and edit them later without extra setup.

### 1. Insert inline math

- Type `$$your-latex$$` to instantly convert it into inline math.
- Or open the toolbar and click **Inline Expression** (radical icon). If you have text selected, it becomes the LaTeX body.

### 2. Insert block math

- Use the toolbar **Block Expression** (square root icon) or the `/` slash menu and pick **Math → Block Expression**.
- A block equation appears on its own line; replace the default `a^2 + b^2 = c^2` with your LaTeX.

### 3. Edit an existing equation

- Click any math node (inline or block). A prompt appears with the current LaTeX.
- Update the LaTeX and confirm to re-render the expression.

### 4. Quick tips

- Inline math stays within a sentence; block math is best for standalone equations or derivations.
- Use standard KaTeX/LaTeX syntax (fractions, roots, superscripts/subscripts, Greek symbols, etc.).
- You can mix math with other formatting, tables, and media in the same document.
