you have a point there, the version i remember did not place a restriction of 4 weights to the solution.

You can weigh a 2 by putting a three on one side, and a one on the other. Ditto for 5 (9 vs 3+1)

It's an old problem from pre revolution France. The conventional way of thinking was that the mass being weighed on the balance had to be measured with a number of the weights on the opposite side. The solution here is to realise that you can also add weights to the side being weighed. So 1 is weighed conventionally but 2 is weighed with a 3 on one side and a 1 being added to the side being weighed, etc 1, 1 2, 3, 1 3, 3 4,3,1 5,9,3,1 6,9,3 7,9,1,3 8,9,1 9,9
