80 on an abacus

To show 80 on a soroban, read the rods from left to right: the millions column is clear with no active beads; the hundred-thousands column is set to zero; the ten-thousands column has no beads moved to the beam; the thousands column remains empty on this column; the hundreds column is clear with no active beads; the tens column marks 8 with the top bead touching the beam and 3 lower beads raised; the ones column has no beads moved to the beam.

1. Step 1. Start from a cleared soroban with every upper bead away from the beam and every lower bead resting at the bottom.
2. Step 2. Adjust the millions column to 0. the millions column is clear with no active beads.
3. Step 3. Configure the hundred-thousands rod for 0. That means the hundred-thousands column is set to zero.
4. Step 4. On the ten-thousands column, show 0. In practice, the ten-thousands column has no beads moved to the beam.
5. Step 5. Set the thousands column for 0. Here, the thousands column remains empty on this column.
6. Step 6. Adjust the hundreds column to 0. the hundreds column is clear with no active beads.
7. Step 7. Configure the tens rod for 8. That means the tens column marks 8 with the top bead touching the beam and 3 lower beads raised.
8. Step 8. On the ones column, show 0. In practice, the ones column has no beads moved to the beam.
9. Step 9. Once every column is set, the soroban should read 80 across the full frame.
