I am having trouble typing in negative numbers for uneven cashflow NPV’s. (using HP 12C)
I have only just started using it so I am probably doing something wrong.
When I input negitive numbers for CFj they stack and an unwanted subtract sum takes place.
EG: CF1=100 CF2=-200 …
I enter it as follows 100 [g] [CFj] 200 - [g] [CFj] (the problem is doing this will compute 200-100)
is there a way to put this in correctly without clearing the previous number before writing in a negative input,
