Hi all,

I am new to this forum. Recently, I am excited by the HP 15C limited edition and trying to recall the memory of using my Singapore version of HP 12C as well.

Back to the subject, I want to calculate the principal which will accumulate to $10,000 at simple rate 7% p.a. over two years.

FV = 10,000

i = 7

n =2

The PV is calculated as -8,734.39.

As you may know, this is not correct given the formula PV*(1+2*0.07)=10,000. The correct PV should be 8,771.93

I figure out that it is the default compound interest calculation in HP 12C.

My question is that is there a way to make HP 12C use simple interest method to work out the PV? I understand there is a key STO EEX for old period calculation but it seems that is not useful here.

I would appreciate your assistance. Many thanks.

Sam
