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 x^{2}, but can make your text more readable when you want to state that $p: s\leadsto t$ or compute

(1) \begin{align} \frac{1}{\sqrt{\pi}}\int_{-\infty}^{\infty} e^{-x^2}dx \end{align}

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]].
