#### 9.2.13 MathJax Support

As an extension to the original Markdown spec from John Gruber, MathJax Version 3 is supported.

MathJax is off by default. It must be enabled on the Collection Settings before it can be used.

Notenik uses an internal copy of MathJax, so it shouldn’t require an active Internet connection to display properly.

Notenik generally follows the MultiMarkdown conventions in terms of syntax.

Here’s one way to code math within a paragraph, starting with \$$ and ending with \$$.

First the code:


Here's an example of math within a paragraph --- \$${e}^{i\pi }+1=0\$$
--- easy enough.


And then the result:

Here’s an example of math within a paragraph — $${e}^{i\pi }+1=0$$ — easy enough.

And here’s a second way to code math wihin a paragraph, using dollar sign delimiters.

First the code:


An example of math within a paragraph --- ${e}^{i\pi }+1=0$
--- easy enough.


And then the result:

An example of math within a paragraph — $${e}^{i\pi }+1=0$$ — easy enough.

And here’s the first way to code a line of math all on its own, starting with \$ and ending with \$.

First the code:


\${x}_{1,2}=\frac{-b\pm \sqrt{{b}^{2}-4ac}}{2a} \$


And then the result:

$${x}_{1,2}=\frac{-b\pm \sqrt{{b}^{2}-4ac}}{2a}$$

And here’s the second way to code a line of math all on its own, using dollar signs.

First the code:


$${x}_{1,2}=\frac{-b\pm \sqrt{{b}^{2}-4ac}}{2a}$$


And then the result:

$${x}_{1,2}=\frac{-b\pm \sqrt{{b}^{2}-4ac}}{2a}$$

You should know that Notenik depends on sensible and conventional spacing and punctuation to avoid confusing multiple dollar figures with a run of math – as in the following example.

Add $50 to$150 and you get \$200.
