Example:
| £ | s. | p. |
| 178 | 13 | 3 |
| 526 | 9 | 7 |
| 3476 | 6 | 11 |
| 216 | 3 | 2 |
| 1276 | 16 | 4 |
| 316 | 19 | 11 |
| 124 | 17 | 3 |
Adding up the pence, we have 41. Placing our fingers on the keys (red 11) to divide by 12, we find, after three strokes, that there are 3s and 5d. Leaving this stand on the register and adding up the shillings on the fourth and fifth columns, the register indicates 86s 5d.
Now divide the 86s by 20 (red 1 in the fourth column is the only key used in this case). Four strokes performs the division, when the register indicates £4 6s 5d. Then adding the pounds on the fifth and higher columns the answer, £6116 6s 5d, is shown by the register.
