| B1 | (indep) for correct key, eg 16|0 or 160|0 represents 160 |
Additional guidance
Accept stem of 160, 170, 180, 190
Can be in reverse vertical order (with matching leaves) eg 19, 18, 17, 16
Errors can be omissions; one number in the wrong position is one error.
Key must be consistent with the stem.
