I still think the problem is to come up with a total of 100 - adding numbers, but not using negative numbers - just positive numbers, although they can be decimals. There are many ways to arrive at 100 if negative numbers are used, so that is not much of a problem.

My question is: is there really a solution if only positive numbers are used? The original post implied that, but did not state it. It also implied addition as the only mathematical operation.

I have spent a few hours playing with it, using excel to do the arithmatic, but always was a shade off the desired result. It is a fun puzzle - given the restriction above. But I am not sure it has a solution.
