How to use matrix notations in my posts?

Ronankeating

Hi all,

I'm pretty new with how to use HTML text editor effectively when posting the new threads. Generally I can deal with math/physics symbols on the editor bar but don't now how to write that huge square brackets for, say 10x10, matrix and populate it.

Regards,

I find I have to do a little more:

• Right-click it
• Click or move cursor to "Show Math As"
• Click "TeX Commands"
