Synopsis:

\begin{displaymath}mathematical text\end{displaymath}

Environment to typeset the `mathematical text` on its own line, in display style and centered. To make the text be flush-left use the global option `fleqn`

; see Document class options.

In the `displaymath`

environment no equation number is added to the math text. One way to get an equation number is to use the `equation`

environment (see equation).

LaTeX will not break the `math text` across lines.

Note that the `amsmath` package has significantly more extensive displayed equation facilities. For example, there are a number of ways in that package for having math text broken across lines.

The construct `\[`

is a synonym for the environment `math`\]`\begin{displaymath} `

but the latter is easier to work with in the source; for instance, searching for a square bracket may get false positives but the word `math` \end{displaymath}`displaymath`

will likely be unique.

(Aside: The construct `$$`

from Plain TeX is sometimes mistakenly used as a synonym for `math`$$`displaymath`

. It is not a synonym, and is not officially supported in LaTeX at all; `$$`

doesn’t support the `fleqn`

option (see Document class options), has different vertical spacing, and doesn’t perform consistency checks.)

The output from this example is centered and alone on its line.

\begin{displaymath} \int_1^2 x^2\,dx=7/3 \end{displaymath}

Also, the integral sign is larger than the inline version `\( \int_1^2 x^2\,dx=7/3 \)`

produces.
