Hi, I just bought the BA II PLUS financial calculator for my financial management class and I dont really understand the user manual. So for example, a collectionnor buy a painting for 2 million dollars and he think that in 5 years, he can sell it 4 million, How do I find the discount rate with the calculator? I know How to find it when I write it down but I'm searching a quicker way with the calculator... Thank you for your help! I tried as you said but it gave me a error message (Error 5) ???
