Question 190228: If the digits 1 through 9 were written in order, it is possible to place plus and minus signs between the numbers or to use no operation symbol at all to obtain a total of 100. Example: 1+2+3+-4+5+6+78+9=100
Can you obtain a total of 100, using fewer plus or minus signs than in the given example? Note that digits, 7 and 8 in the example may be combined.

Here's another way to obtain 100 (there may be other ways):

123+45-67+8-9=100


With these types of problems you have to get creative and hope you get lucky and find (one of) the answer(s).
