Hello there. I noticed that you had some problems with superscripts and the like. If you want to write v2 then type v<sup>2</sup>. The <sup> tells the site that you want anything following to be a superscript. The </sup> tells it that you've finished with superscripts. It's the same with subscripts: If you want to write v2 then type v<sub>2</sub>.
This works for lots and lots of things:
For bold text, type <b>test</b> to get test.
For Italics, type <i>test</i> to get test.
For underlined, type <u>test</u> to get test.
For teletext font, type <tt>test</tt> to get test.
If you want to write and display code, like I've been doing, without the site turning it into bold or whatever, then use <nowiki><b>test</b></nowiki> to get <b>test</b>.
