To make the text be flush-left use the global option 0136 <code>fleqn</code>; see <a href="Document-class-options.html#Document-class-options">Document class options</a>. 0137 </p> 0138 <p>In the <code>displaymath</code> environment no equation number is added to the 0139 math text. One way to get an equation number is to use the 0140 <code>equation</code> environment (see <a href="equation.html#equation">equation</a>). 0141 </p> 0142 <p>LaTeX will not break the <var>math text</var> across lines. 0143 </p> 0144 <a name="index-package_002c-amsmath-2"></a> 0145 <a name="index-amsmath-package-2"></a> 0146 0147 <p>Note that the <samp>amsmath</samp> package has significantly more extensive 0148 displayed equation facilities.

(The construct 0156 <code>$$<var>math text</var>$$</code> from Plain TeX is sometimes 0157 mistakenly used as a synonym for <code>displaymath</code>. It is not a 0158 synonym, because the <code>displaymath</code> environment checks that it isn’t 0159 started in math mode and that it ends in math mode begun by the matching 0160 environment start, because the <code>displaymath</code> environment has 0161 different vertical spacing, and because the <code>displaymath</code> 0162 environment honors the <code>fleqn</code> option.) 0163 </p> 0164 <p>The output from this example is centered and alone on its line. 0165 </p> 0166 <div class="example"> 0167 <pre class="example">\begin{displaymath} 0168 \int_1^2 x^2\,dx=7/3 0169 \end{displaymath} 0170 </pre></div> 0171 0172 <p>Also, the integral sign is larger than the inline version 0173 <code>\( \int_1^2 x^2\,dx=7/3 \)</code> produces. 0174 </p> 0175 0176 0177 0178 <hr/><div class='referenceinfo'> <a href='https://latexref.xyz/'> <i>Unofficial LaTeX2e reference manual</i></a></div> 0179 </body> 0180 </html>
