I wonder assigning same value to two variables and reassigning the different value would change everything. What do you mean by it changes everything? Basically how it functions is the variables take the value from ANS i.e. previously entered or calculated value from memory. In fact, you can get the ANS manually as well if you like by pressing 2nd ANS

Here is what you are trying now: 3 N enter PV FV.

N=3, FV=1000, I/Y=10, PMT=-100, PV=?
You should follow these key strokes for the above problem: 2nd clear TVM 3 N enter 1000 FV enter 10 I/Y enter 100 +/- PMT enter CPT PV
