Writing in Hebrew
If you write in Hebrew, you should wrap your text with a right-to-left div to give it the right direction.
To do this, simply write [[div style="direction:rtl;"]] before the text and [[/div]] after (each on a separate line!).
This is especially important if you mix Hebrew and English, as the following example shows.
| Without a div | With a div |
| יהי G גרף לא מכוון בעל n צמתים ו-m קשתות. |
יהי G גרף לא מכוון בעל n צמתים ו-m קשתות. |
Using mathematical notations
If you want to include math in your post, and know some TeX, you can use it in your posts. This may not be necessary just to write x2, but can make your text more readable when you want to state that $p: s\leadsto t$ or compute
(1)To use inline TeX, write it between [[$ and $]] (e.g., [[$\frac{1}{\sqrt{2}}$]] gives $\frac{1}{\sqrt{2}}$).
To use an equation on a whole line, write it between [[math]] and [[/math]].
