The soroban is a powerful tool for mental arithmetic. To use it, you must first learn the value of each bead and how to represent numbers. The top beads (heaven beads) are worth 5, and the bottom beads (earth beads) are worth 1. Beads are 'activated' or 'counted' when they are moved towards the horizontal bar.
