You can't do that.  Store it to a string, I mean.  The 82 doesn't have
string capabilities.  I think that you have to store it into a y=
variable, which will of course require quotation marks :(  On the _83_
you can store the equation as a string and then use the string to
equation command to convert the string into a y=.  This allows you to
avoid using the quotation marks. :)
