Enabling Math

The Math plugin can be enabled from its settings, accessed from your admin/plugins page:

Features

Once enabled, you can render inline math by wrapping with a single $ like so: $E=mc^2$.

You can render blocks of maths by wrapping with $$

$$
\sqrt{(-1)} \; 2^3 \; \sum \; \pi
$$

Discourse Math uses a heuristic to ensure that sentences such as: β€œI spent 20$ and another 100$” do not get converted.

When using MathJax, you can also enable asciimath processing which uses % as a delimiter: %E=mc^2%

Site Settings

  • See all relevant site settings by searching your admin settings for β€œmath”
