Some "math" symbols are obtained by typing the corresponding  keyboard 
character.  Examples include
<pre> + - = &lt; &gt; </pre> 
<strong>Note:</strong> plus, minus, and equal sign may be used in
either text or math mode, but &lt; and &gt; are math mode only 
(they produce inverted exclamation and question marks, respectively,
in text mode).
<p>
The following commands may be used only in math mode.

<ul>
<li><tt>\pm</tt> plus or minus sign 
<li><tt>\mp</tt> minus or plus sign
<li><tt>\times</tt> times (an "x") 
<li><tt>\div</tt> divided by sign
<li><tt>\ast</tt> an asterisk (centered)
<li><tt>\star</tt> a five-point star (centered) 
<li><tt>\bullet</tt> a bullet
<li><tt>\circ</tt> an open bullet
<li><tt>\cdot</tt> a centered dot (see also, 
     <a href="ltx-207.html"><tt>\cdots</tt></a>)
<p>
<li><tt>\leq</tt> less than or equal to
<li><tt>\ll</tt> much less than 
<li><tt>\subset</tt> is a subset of
<li><tt>\geq</tt> greater than or equal to 
<li><tt>\gg</tt> much greater than 
<li><tt>\equiv</tt> equivalence symbol
<li><tt>\sim</tt> similar to 
<li><tt>\simeq</tt> similar or equal to
<li><tt>\approx</tt> approximately equal to 
<li><tt>\neq</tt> not equal to
<li><tt>\per</tt> "perpendicular to" symbols
<li><tt>\propto</tt> proportional to
</ul>
<p>
Note that "greater than" and "less than" are obtained simply by
entering <tt>&gt;</tt> and <tt>&lt;</tt>.
<p>
A slash, indicating <a name=not>"not"</a> can be placed through a symbol
(or a letter) with the <tt>\not</tt> command.  For example, not less than is
<pre>  \not&lt;  
</pre>
and not less than or equal to is
<pre> \not\leq
</pre>
If the slash isn't properly positioned it can be moved by putting a
<a href="ltx-118.html">math mode spacing command</a> between the <tt>\not</tt>
and the symbol.
