One solution to your problem is to go to
http://www.research.att.com/~njas/sequences/
a site that analyzes sequences. It will give you lots of ways the numbers you
are looking at could be elements in a sequence. Another thought is to use a
computer algebra system to look at all the different ways you could add,
subtract, divide the different digits. I know you could do it in Mathematica but
am not sure about other CASs such as that ona TI89. By the way don't give up
so quickly on the geometric perspective because a lot of nuber theory was
derived by the ancient Greeks who were soperb geometers, Hope the preceeding was
helpful.
