LON-CAPA User Help: <m > tag?

<a href="">LON-CAPA User Help</a> : <a href="">Authoring</a> :
&lt;m &gt; tag?
    Wrapping TeX with <m > </m > will put the TeX through the TTH (tex to html)
    converter.  If you want variables inside of this tag to be evaluated before
    the tex gets converted, then use <m eval="on" >
    
    <m eval="on">\[$eqn\]</m >, will evaluate the variable $eqn first and
    then run it through the TTH converter.
    
    The following will get rid of +- and convert it to - inside of
    equations:
    <script >
    ...
    $eq = "$a + $b"; $eq = ~s/\+-/-/s; </script >
    In text area:
    <m eval="on" >$eq</m >
