Originally, to include Tex and Latex maths in the forum, you could use dollardollar...dollardollar and \open square bracket...\close square bracket for displayed mathematics (on a new line displayed centrally), and backslash(...backslash) for in-line mathematics.
Latex normally allows the use of a single dollar sign, dollar...dollar, instead of backslash(...backslash), but to avoid problems with text which contains dollar signs, MathJax does not implement it as standard, but gives you the option of allowing it if you wish.
I have now implemented the use of the single dollar sign as an alternative. I don't think it will cause many problems on this forum, as we will probably not be discussing money! However, should the necessity ever arise there is always the alternative, which still works.
Note: in the above text the words dollar,square bracket, backslash, should be replaced by the symbols, in a real situation.
Please check out this link for a full explanation.
Here is an example:
When $a \ne 0$, there are two solutions to \(ax^2 + bx + c = 0\) and they are
$$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$
and the same example using the alternative codes for:
When \(a \ne 0\), there are two solutions to $ax^2 + bx + c = 0$ and they are
\[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
