Reading the abacus from the highest place value to the units column, 1234 appears as follows: the millions column has no beads moved to the beam; the hundred-thousands column remains empty on this column; the ten-thousands column is clear with no active beads; the thousands column shows 1 with the upper bead inactive and 1 lower bead pushed up; the hundreds column shows 2 with the upper bead inactive and 2 lower beads pushed up; the tens column shows 3 with the upper bead inactive and 3 lower beads pushed up; the ones column shows 4 with the upper bead inactive and 4 lower beads pushed up.
- Step 1. First clear the frame so no rod is counting: top beads off the beam and lower beads fully lowered.
- Step 2. On the millions column, show 0. In practice, the millions column has no beads moved to the beam.
- Step 3. Set the hundred-thousands column for 0. Here, the hundred-thousands column remains empty on this column.
- Step 4. Adjust the ten-thousands column to 0. the ten-thousands column is clear with no active beads.
- Step 5. Adjust the thousands column to 1. the thousands column shows 1 with the upper bead inactive and 1 lower bead pushed up.
- Step 6. Adjust the hundreds column to 2. the hundreds column shows 2 with the upper bead inactive and 2 lower beads pushed up.
- Step 7. Adjust the tens column to 3. the tens column shows 3 with the upper bead inactive and 3 lower beads pushed up.
- Step 8. Adjust the ones column to 4. the ones column shows 4 with the upper bead inactive and 4 lower beads pushed up.
- Step 9. Check each place value in order to verify that the abacus now shows 1234.
