Solved!

10bii Future Value and Present Value wrong answers

HP Recommended

Hye, same as mine, actually that not wrong answer but depending on your P/YR, if P/YR set to 12, you will get different answer, how to know P/YR is 12?you press [GOLD Shift][C ALL], it will display 12 P_yr,

 

So, how to set P/YR to 1,

Press [Gold shift] [C ALL] and then press 1 [Gold Shift] [P/YR].... Now the calculator is set to assume 1 period/year. To confirm this setting, press and hold [Gold Shift] [C ALL]. Unless needed for other work, we generally leave the calculator setting at 1 period per year.

 

***if you reset the calculator, the default P/YR is 12

You can also recall it without clearing anything else, by pressing [RCL] [gold shift] [P/YR].

Note, reset means "completely wipe all memory and reset the device to factory".

 

Just doing a C-ALL will NOT change the P/YR setting. That will be retained to what you have it set to before the clear.
