How to use matrix notations in my posts?

    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.

    I find I have to do a little more:
    • Right-click it
    • Click or move cursor to "Show Math As"
    • Click "TeX Commands"
