A pandigital is an integer containing every digit.  In this
particular case, we're dealing with 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 of 100.  For example,

123 + 45 - 67 + 8 - 9 = 100

Are 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?

THE SOLUTION

Mr. Ellis wrote a basic program which can be seen at
http://www.puzzlet.co.uk/Solutions/Puzzlet_002_sol.html
which generated these twelve solutions.

123-45-67+89 = 100
123+45-67+8-9 = 100
123+4-5+67-89 = 100
123-4-5-6-7+8-9 = 100
12+3-4+5+67+8+9 = 100
12-3-4+5-6+7+89 = 100
12+3+4+5-6-7+89 = 100
1+23-4+56+7+8+9 = 100
1+23-4+5+6+78-9 = 100
1+2+34-5+67-8+9 = 100
-1+2-3+4+5+6+78+9 = 100
1+2+3-4+5+6+78+9 = 100
