Math Expressions

This page demonstrates how to include mathematical expressions.

Individual pages can opt-in to supporting mathematical notation using MathJax, so that you can write expressions with LaTeX syntax, either inline or as a block.

Processing a page with MathJax can take a few seconds, so it is not enabled by default on all pages.If you want to use MathJax, you must enable it in the front matter of your page (i.e. add "mathjax" to extensions:

extensions: ["mathjax"]

In your page content, math expressions are delineated by $$ tags before and after the expression.

Block equation example


$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}$$


\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}\]

Inline equation example


When $$a \ne 0$$, there are two solutions
to $$(ax^2 + bx + c = 0)$$.


When \(a \ne 0\) , there are two solutions to \((ax^2 + bx + c = 0)\).
