I’m going over the practice problems for Reading 5. When I do the command functions to try to solve for r or n like in problems 16 and 17 I keep getting an Error 5 message. Does anyone know why this is? for example 17 solving for N I do the steps below. 1st Press 5/12 then I/Y 2nd Press 35,000 then PV 3rd Press 0 then PMT 4th Press 100,000 then FV 5th Press CPT then N Thanks

you must either enter the PV or FV as a negative number. Best of Luck

Thanks you very much!!!
