Product: Financial Calculator HP 10bII+
Operating System: Other

I have been calculating problems along with the homework my instructor has been going over in class and have been getting different answers. For example, we are finding annuity due, so I moved my calculator to begin mode. It is 528 months, 0.825 interest a month, -$350 a month, and obviously we are finding future value. So I put in N = 528, I/YR = 0.825, PMT = -350, and then I click FV. My calculator gave me $222,858.27, but my entire class and the online calculator I used gave me $3,232,201.79. Clearly the answer they all got is correct, so why am I getting something different when I plugged in the formula the exact same way several times? Also, I did a full memory reset and clear to make sure I'm not missing anything. Anything helps, please help me fix this!!
