+# LaTeX Math
+
+With the flag `MD_FLAG_LATEXMATHSPANS`, MD4C enables extension for recognition
+of LaTeX style math spans.
+
+A math span is is any text wrapped in dollars or double dollars (`$...$` or
+`$$...$$`).
+
+```````````````````````````````` example
+$a+b=c$ Hello, world!
+.
+<p><x-equation>a+b=c</x-equation> Hello, world!</p>
+````````````````````````````````
+
+If the double dollar sign is used, the math span is a display math span.
+
+```````````````````````````````` example
+This is a display equation: $$\int_a^b x dx$$.
+.
+<p>This is a display equation: <x-equation type="display">\int_a^b x dx</x-equation>.</p>
+````````````````````````````````
+
+Math spans may span multiple lines as they are normal spans:
+
+```````````````````````````````` example
+$$
+\int_a^b
+f(x) dx
+$$
+.
+<p><x-equation type="display">\int_a^b f(x) dx </x-equation></p>
+````````````````````````````````
+
+Note though that many (simple) renderers may output the math spans just as a
+verbatim text. (This includes the HTML renderer used by the `md2html` utility.)
+
+Only advanced renderers which implement LaTeX math syntax can be expected to
+provide better results.
