Say if we were to find the past value of $1 at an interest rate of 5% for the 10 years past today.

If we were to use the present value formula

where

It seems like the past value of $1 is kind of like future value of $1(Thinking)

Does this make sense?

To me it kind of does, since a dollar in hand today is worth less than a dollar we had 10 years ago

Would someone here comment on these findings
