&lt;i&gt;&lt;b&gt;Rule:&lt;/b&gt;&lt;/i&gt;


Whenever you multiply an inequality by a negative number, reverse the sense of the inequality.  That is *[tex \Large &gt;] or *[tex \Large \geq] becomes *[tex \Large &lt;] or *[tex \Large \leq] or vice versa.


The reason that the rule &lt;i&gt;doesn&#39;t&lt;/i&gt; say &quot;Whenever you multiply &lt;i&gt;or divide&lt;/i&gt;...(and doesn&#39;t need to) is left as an exercise for the student.

*[tex \LARGE e^{i\pi} + 1 = 0]
My calculator said it, I believe it, that settles it
