Math#
Write TeX between dollar signs. Sumi typesets it with a bundled copy of KaTeX, loaded only on pages that contain a formula.
Inline formulas#
Euler's identity, $e^{i\pi} + 1 = 0$, links five constants.
Euler's identity, e^{i\pi} + 1 = 0, links five constants.
A dollar sign followed by a space, or preceded by a letter or digit, is not math — so prices such as $5 or $10 stay as written. Escape a literal dollar sign as \$.

$$
\hat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\, e^{-2\pi i x \xi}\, dx
$$
\hat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\, e^{-2\pi i x \xi}\, dx
Multi-line environments work too:
\begin{aligned}
\nabla \cdot \mathbf{E} &= \frac{\rho}{\varepsilon_0} \\
\nabla \times \mathbf{B} &= \mu_0 \mathbf{J} + \mu_0 \varepsilon_0 \frac{\partial \mathbf{E}}{\partial t}
\end{aligned}
Compatibility#
If pymdownx.arithmatex is configured with generic: true, Sumi renders its output with the same KaTeX and turns its own $ parsing off. To disable math entirely, set math: false on the plugin.
