# Is the function of Displayed Math Gone?

Hello There,

This might not be the place to ask this question, but I would not know where else to being that it pertains to SE in particular. I was wondering is the functionality of the displayed math mode command gone for use here. The command in which I am talking about is below:

                                 $...$


It seems to work now I see as sample code but not as a functional math related command.

Any explanations on this will be appreciated.

• meta.math.SE is for discussions and questions about and relating to math.SE that do not belong on the main site (being questions that are not mathematical or relating to mathematics itself) such as this one. See the faq for details. – t.b. Jun 1 '11 at 10:44

This question should be asked on meta.math.SE.

For the sake of having a quick answer: You need to use \$...\$

For instance, writing \$\int e^x. \$ gives

$\int e^x.$

Alternatively, you can also use $$...$$. You'll surely get more detailed information shortly.

• Thanks for clarifying what it needs to be. – night owl Jun 1 '11 at 10:10

The strings

\[

and

\(

have meaning in Markdown, per https://math.stackexchange.com/editing-help

Thus, you must escape them. Or to keep it simple, use $ (inline) and $\$ (block) syntax.

$$...$$


also works.

$$\int e^{-x^2/2} dx$$
