71 on an abacus

On a soroban, the number 71 is built with these column positions: the millions column is set to zero; the hundred-thousands column has no beads moved to the beam; the ten-thousands column remains empty on this column; the thousands column is clear with no active beads; the hundreds column is set to zero; the tens column represents 7 by combining the five-bead with 2 lower beads moved upward; the ones column reads 1 because the top bead stays clear while 1 lower bead 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. Configure the millions rod for 0. That means the millions column is set to zero.
3. Step 3. On the hundred-thousands column, show 0. In practice, the hundred-thousands column has no beads moved to the beam.
4. Step 4. Set the ten-thousands column for 0. Here, the ten-thousands column remains empty on this column.
5. Step 5. Adjust the thousands column to 0. the thousands column is clear with no active beads.
6. Step 6. Configure the hundreds rod for 0. That means the hundreds column is set to zero.
7. Step 7. Set the tens column for 7. Here, the tens column represents 7 by combining the five-bead with 2 lower beads moved upward.
8. Step 8. On the ones column, show 1. In practice, the ones column reads 1 because the top bead stays clear while 1 lower bead are slid up.
9. Step 9. Finish by scanning the rods from the highest place to the units column and confirm the result is 71.
