A short mathematical note

Write Markdown and mathematics together. Your preview updates as you type.

Inline mathematics

The right-triangle relation $a^2+b^2=c^2$ uses bracket delimiters. Euler's identity $e^{i\pi}+1=0$ uses dollar delimiters.

Display mathematics

$$\int_0^1 x^2\,\mathrm{d}x = \frac{1}{3}$$ $$\begin{aligned} (x+y)^2 &= x^2+2xy+y^2, \\ (x-y)^2 &= x^2-2xy+y^2. \end{aligned}$$

A small table

Notation	Meaning
$x$	A real variable
$x^2$	Its square

A useful note can combine prose, equations, lists, and code.

Markdown and PDF tips

Headings, lists, links, tables, blockquotes, and fenced code blocks are supported. Math inside code stays literal. HTML is shown as text. External images are not loaded; embedded raster images are supported.

Save as PDF opens the print dialog. Choose its PDF destination and turn off browser headers and footers for a clean document. Only your rendered content is exported. For very wide mathematics, choose landscape or split the equation into aligned lines.

Download Markdown keeps an editable copy. This tool does not save drafts between visits.

When the panels are side by side, scrolling either one follows the corresponding section in the other. Turn off Sync scrolling to browse them independently.
