The number of payments keyed in just before f! is pressed is taken to be the
payments following any that have already been amortized. Thus, if you now press

Pressing :$ or :n displays the number in the PV or n register. When you
did so after each of the last two calculations, you may have noticed that PV and n

0.

each of the first two months:
