Simply press the 

 key and the HP calculates the rate of return to be 12.18 percent.

I/YR

Remember that the HP is programmed so that if the PV is + then the FV is displayed as - and vice versa
because the HP assumes that one is an inflow and other is an outflow.  When entering both PV and FV
values, one must be negative and one positive.

Now suppose you learn that the bond will actually cost $300.  What rate of return will you earn?

Override

 the -200 by entering 300 

 

, then press 

 to get 8.98 percent.  If you pay more

+/-

PV

I/YR

for the bond, you earn less on it.  The important thing, though, is that you can do “what if” analyses with
the calculator.

Now do nothing except 

 

 to turn off the calculator.  Then turn on the calculator 

.  The display

OFF

C

shows 0.00.  Is the memory erased?  Not completely.  What was on the screen is gone, but  press 

 

RCL

N

to get N = 14.  The other memory registers also retain information unless you press  

 

.
