There are currently three ways of writing maths notation directly in a post...

**The first method** is to use \( \LaTeX \). This is a special typesetting language that's easy to learn (see the

Learn \( \LaTeX \) in 30 minutes guide for details).

For example, say I want to write the fraction a half like this:

\[ \frac{1}{2} \]

... so that it actually looks like a fraction. To achieve this then in \( \LaTeX \) I would write the following code:

`\frac{1}{2}`

.

In order to tell the forum that this is \( \LaTeX \) we need to surround the code with special tags like this:

`[latex]...[/latex]`

So, the following:

`[latex]\frac{1}{2}[/latex]`

... is rendered as:

\[ \frac{1}{2} \]

If you want the notation to appear in a line of text (like this: \( y=mx+c \) then use the 'inline' flag like this:

`[latex=inline]y=mx+c[/latex]`

**The second method** is to use the built-in \( \LaTeX \) editor based on fMath - see the button with the '\( \pi \) and pencil' icon in the text editor when you write your post. I'm in the process of writing a blog post on this feature so there'll be more information on this soon!

**The third method** is to write out your question, take a photo and then attach it to a post using the

**Attachments and other options** settings underneath the text editor. This is the easiest option but watch out for the file size limit.

As ever, if you have any questions then please ask!
