@abhishek has kindly agreed to enable the `math`

plugin for our itsFOSS forum posts. There is a description here

I think we have the default `MathJax`

renderer. It based on Latex, but it is only the math rendering part of Latex, not a full Latex.

It is not as if we need to use equations in our replies, but it could be useful occasionally for simple bits of algebra

Example 1:

If I type in

```
The area of a circle is $\pi r{^2}$
```

I get

The area of a circle is \pi r{^2}

That is the way to do math in the middle of a sentence… enclose it in `$`

symbols.

Example2:

Suppose I want a block of equations.

If I type

```
$$
x = \frac{y + z/2}{y^{2}+1
z = \sqrt{x + y}
$$
```

I get

x = \frac{y + z/2}{y^{2}+1} \\
z = \sqrt{x + y}

For those not familiar with Latex math cheat sheet here

and the fullLatex documentation is the classic book

I

Do not expect to be able to do non-math Latex commands such as tables. It does not work.

Thanks to you both for that option.

You can use it with numbers instead of symbols

so 37/2 = 18.5 is the answer

That came from

```
so $37/2 = 18.5$ is the answer
```

Notice the numbers are a different font compared to

so 37/2 = 18.5 is the answer

\pounds 24

Yep, it works

\texteuro 345

`\euro does not work ?`

According to this

https://docs.mathjax.org/en/latest/input/tex/macros/index.html

`\texteuro`

should work

but it does not work for me here
