HP 28C - Too Few Arguments

[Brad Barton]

Steve's test should help illuminate the basics of RPN operation. You can also read up at the following link for a deeper explanation (http://www.hpmuseum.org/rpn.htm). RPN will seem a little foreign to you initially, but after 15 or 20 minutes it will be 2nd nature. It's so ingrained in my brain that I have trouble using a standard calculator. RPN just makes more sense to me.

Also, the 1: 2: and 3: are normal to see on the display, as is shown in this picture (http://www.hpmuseum.org/img/28cs.jpg) of a 28C. These numbers label the stack level that you will learn about by reading the first link.

The "Too Few Arguments" error message usually comes as a result of trying some operation without enough arguments on the stack. For example if you press the "+" button (or any other operation requiring 2 arguments) with only 1 number on the stack, you would get this error.

Good luck with your new calculator, and let us know if you have further questions.
