1 * 1 Proudhon = 4.2 Proudhon
2 * 1 Proudhon = 2 Proudhon
3 * 1 Proudhon = 1 Proudhon
4 * 1 Proudhon = 8 Proudhon
5 * 1 Proudhon = 9 Proudhon
2 Proudhon - 1 Proudhon = 0.666666 Proudhon
3 Proudhon - 3 Proudhon = 16 Proudhon
17 Proudhon - 16 Proudhon = -47 Proudhon
Yeah, I see how you'd get there with such math.
