9,999,999 on an abacus

On a soroban, the number 9999999 is built with these column positions: the millions column shows 9 with the upper bead active and 4 lower beads pushed up; the hundred-thousands column marks 9 with the top bead touching the beam and 4 lower beads raised; the ten-thousands column reads 9 because the upper bead is engaged and 4 lower beads are slid up; the thousands column represents 9 by combining the five-bead with 4 lower beads moved upward; the hundreds column shows 9 with the upper bead active and 4 lower beads pushed up; the tens column marks 9 with the top bead touching the beam and 4 lower beads raised; the ones column reads 9 because the upper bead is engaged and 4 lower beads are slid up.

1. Step 1. Set the soroban to zero before you begin, keeping the upper beads separated from the beam and the lower beads at rest.
2. Step 2. Adjust the millions column to 9. the millions column shows 9 with the upper bead active and 4 lower beads pushed up.
3. Step 3. Configure the hundred-thousands rod for 9. That means the hundred-thousands column marks 9 with the top bead touching the beam and 4 lower beads raised.
4. Step 4. On the ten-thousands column, show 9. In practice, the ten-thousands column reads 9 because the upper bead is engaged and 4 lower beads are slid up.
5. Step 5. Set the thousands column for 9. Here, the thousands column represents 9 by combining the five-bead with 4 lower beads moved upward.
6. Step 6. Adjust the hundreds column to 9. the hundreds column shows 9 with the upper bead active and 4 lower beads pushed up.
7. Step 7. Configure the tens rod for 9. That means the tens column marks 9 with the top bead touching the beam and 4 lower beads raised.
8. Step 8. On the ones column, show 9. In practice, the ones column reads 9 because the upper bead is engaged and 4 lower beads are slid up.
9. Step 9. Finish by scanning the rods from the highest place to the units column and confirm the result is 9999999.
