My TI BA II Plus is returning incorrect answers for TVM problems... Is this common and can it be fixed?

Let's see, 10% interest per year on $100 for one month. That's 10/12 of a percent interest on $100 is $0.83, added to $100 is $100.83 (with a bunch more 3s at the end). Clearly this is the correct answer. What answer are you expecting? The future value at the end of one year instead of one month?

Everytime i calculate for the IRR, it says rst 0.00

I had the exact same problem, after multiple resets I realised the problem was low battery. I measured the voltage and it was indeed 2.8v when it should be closer to 3.3v. try replacing the battery and it will work fine.

FV wrong answers

Were you also clearing the financial memory with 2nd [CLR TVM], or just the storage memory? If you don't, it's going to keep using whatever value you last used for PMT.

Exponential Function How is my operation on my calculator

Good morning Cesar The guide for you calculator can be found here https://education.ti.com/en/us/guidebook/details/en/ADF11FB65B284B6195B0A7E9502784BA/baiiplus If you go to page 12, you'll see that this operation, for 42.2 to the 1.56 power would be done with [42.2] [Y^X][1.56][=] You could also do this with [42.2][ln][X][1.56][=][e^X] to do it with logarithms (which is how the calculator is doing it as well).
