Start with the sequence of non-zero digits 123456789. The problem is to place plus or minus signs between them so that the result of thus described arithmetic operation will be 100. THERE IS ABOUT 13 SOLUTIONS TO IT... YOUR JOB IS SIMPLE..... JUST FIND 6 OF THEM..... AND YES ..... AT LEAST ONE SOLUTION SHOULD INVOLVE FACTORIALS AS WELL!!! THIS IS A QUESTION ASKED TO ME BY MY COUSION BROTHER... TILL NOW I HAVE PRODUCED 8 SOLUTIONS.... I POST TWO OF THEM...

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