An abacus is a timeless tool designed to help count and calculate. Can it also count stories and future? Beads are grouped in three sections: on the left side, on the right side and in the middle. The beads' size can vary per line.
I remember having one when I was very young. Multi-colored and pretty big. I never knew how to use it so I just rocked the beads from a side to another to sort them.
