# MathJax and LaTeX

This jekyll-theme supports MathJax to render $\LaTeX$ and mathematics expressions.

## TIP

Currently, Kramdown uses double dollar sign delimiters for inline and display math: https://kramdown.gettalong.org/syntax.html#math-blocks.

e.g.,

```
The well known Pythagorean theorem $x^2 + y^2 = z^2$ was
proved to be invalid for other exponents.
Meaning the next equation has no integer solutions:
$$ x^n + y^n = z^n $$
```

The well known Pythagorean theorem $x^2 + y^2 = z^2$ was proved to be invalid for other exponents. Meaning the next equation has no integer solutions:

\[x^n + y^n = z^n\]Another example with more complex markups:

```
When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
```

When $a \ne 0$, there are two solutions to $ax^2 + bx + c = 0$ and they are

\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]Refer to the MathJax website for more examples.
