Change one number in a calculation without reentering everything? - userx14 - 04-14-2017 08:36 PM
Hello Forum, if I have a equation which is quiet nested, and I realize that one number in the calculation was incorrect, is there a possibility that I can modify the number after i have already finished the calculation? I tried it on a Hp 50, but the "undo" button only reverted the calculation by one step. On my fx9860g I could just edit every part of the equation and press enter to get an updated result. Is this possible with RPN? Can one undo to a certain step an then redo the calculation with a simple buttonpress? I'm sorry if the answer is obvious, because I'm new to Hp&Rpn... Thank you for your answers. |
