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.

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?

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).

Happy New Year!
