Make 100 From A PanDigital
Puzzlet 002 is based on what is known as the Pandigital: an integer
containing every digit. In this particular case, we're dealing
the 9-digit Pandigital, since the zero isn't used.
Take all the digits 1 through 9 in order, and insert as many plus and
minus signs as you wish, wherever you want, to make an arithmetic sum
Example: 123 + 45 - 67 + 8 - 9 = 100
there any more ways of punctuating a 9-digit Pandigital with plus
and minus signs to make a sum of 100 as in the example above? If
so, what are they?
Versions of this poser have been around a long time, but my solution
contains something I've never seen before. Can you find it for
