If the digits 1 through 9 are 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. For 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, such as 7 and 8 in the example, may be combined.
