100 on an abacus

To show 100 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 represents 1 by keeping the upper bead away from the beam and moved upward 1 lower bead; the tens column is set to zero; 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. Set the hundreds column for 1. Here, the hundreds column represents 1 by keeping the upper bead away from the beam and moved upward 1 lower bead.
7. Step 7. Configure the tens rod for 0. That means the tens column is set to zero.
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 100 across the full frame.
