Quarkdown natively supports TeX math equations and formulas. When rendering to HTML, this feature is powered by MathJax.

Inline

Inline formulas can be created by wrapping text between two $ symbols. Both delimiters must be preceded and followed by a whitespace (or beginning/end of the line).

Let $ \overline v = \frac {\Delta x} {\Delta t} $ be the **average velocity** of an object.

One-line block

Block formulas are usually visually centered, and can be created as with inline ones, as long as it's isolated from other inline content:

The following function is a **Fourier Transform**:

$ F(u) = \int^{+\infty}_{-\infty} f(x) e^{-i 2\pi x} dx $

[!NOTE] This syntax does not interrupt paragraphs, so make sure to space blocks properly. If the paragraph is not interrupted, the formula is recognized as inline, due to Markdown's lazy lines:

The following function is a **Fourier Transform**:
$ F(u) = \int^{+\infty}_{-\infty} f(x) e^{-i 2\pi x} dx $

Multiline block

A block formula can span over multiple lines thanks to a syntax similar to fenced code blocks, though using three $ symbols as delimiters:

$$$
f(x) =
\begin{cases}
    0 & \text{if } x = 0 \\
    1 & \text{if } x \neq 0
\end{cases}
$$$
