Start paying with the cut links, 1+1+1+1, at the end of the fifth week, the 5-link piece is given and the 4 one-link pieces are taken back; at the end of the tenth week, the 10-link piece is given and the 4 one-link pieces as well as the 5-link piece are taken back, and so on.

My poor MS cogfoggy mind cannot wrap itself around this. How do you people manage to do this??? I've read it over and over and just cannot grasp it.

I'm a dummy........
