Subject: HTML symbol for "is not equivalent to"

One of the students in the class told me that there is, in fact, an
HTML symbol for "is not equivalent to".

In HW#2, I used "&equiv;" to create the triple-bar symbol for "is
equivalent to".

I have created a new version of that HW using the new symbol,
"&#8802;".

Please take a look and see if it shows up correctly on your browsers.

Oops! When I told you what the symbol was, I had to *use* the symbol!
So you saw the output, not the input. Here's the symbol:

&#8802;

Put that in an HTML document and use a compliant browser, and it should
look like a crossed-out triple bar.
