Pop Quiz Answers

Here are the answers to the Pop Quiz at the beginning of the month.  How many did you get right?  Did you cheat?  :)

1.  Start with the sequence of non-zero digits 123456789. Place plus or minus signs between them so that the result of thus described arithmetic operation will be 100.

Answer:   We got one answer

12 + 3 - 4 + 5 + 67 + 8 + 9 = 100

and suggested there existed at least one more. I do not claim to have made an exhaustive search but there appear to be more than just two answers. One of this is

123 + 4 - 5 + 67 - 89 = 100

I am sure there it at least another one. Want to find it?
