Post Math Contents

For IE, you need to install mathplayer which is free at http://www.dessci.com/en/products/mathplayer/

This means that if you like to post math which is reabable for all popular browsers, use latex instead. The site provide a simple toolbar that works with MathJax from http://www.mathjax.org to handle a subset of latex contents.

Code:
\x=(-b+-sqrt(b^2-4ac))/(2a)\ \ [x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\]

will provide
x=(-b+-sqrt(b^2-4ac))/(2a)
$x=\frac{-b\pm \sqrt {b^2-4ac}}{2a}$

If you don't use the right browser, the 1st line of the result is not a proper math expression as the 2nd line. If you don't familier with latex, you can use our LaTeXBar to start with.

Latex+MathJax make the site privide pretty contents like
$$x = a_0 + \frac{1}{\displaystyle a_1 + \frac{1}{\displaystyle a_2 + \frac{1}{\displaystyle a_3 + a_4}}} \, \, \,$$ and somthing like $$A=\begin{pmatrix} a_{11} & \cdots & a_{1n}\\ \vdots & \ddots & \vdots\\ a_{m1} & \cdots & a_{mn} \end{pmatrix}$$

or even some chemistry $$2H_2 + O_2 \overset{n,m}{\to }2H_2O$$
