Not RPN, just a cheap algebraic calculator.

EE, Amazon
15 January 2015
  • Summary: Has ENTER instead of " = " key, yet is just a cheap, conventional calculator not RPN. Maybe "Enter" mean "Equal" in Portuguese (that's the language of the manual).

Mistaken

Michael Colpetzer, Amazon

  • Summary: Good calculator, NOT RPN, that's what I was looking for. I knew the price was too good to be true. I just assumed with an enter button and no equal button it was. I was not deceived by the seller. Just didn't do my research.

Very pleased with this HP 9s purchase

hazecoy, Ebay
10 September 2012
  • Summary: I wanted tactile keys (feel the click) on my calculator. Hp is the only company I know of that does this. It helps to let you know that you have pressed a key without looking at the screen. The price of this HP 9s was very low and the number of functions exceeds the needs of the normal user.

This is not an RPN calculator

Kurt McClung, Amazon
2 May 2011
  • Summary: Reverse Polish Notation (RPN) calulators use an <enter> key and do not have an <=>. Look closely at the image for this product: This calculator has an <enter> key and does not have a <=> key, but it's not RPN. The owners manual is useless (written in Spanish).

high school calcs

newton fisher "nerdly uncki", Amazon

  • Summary: This calculator was for the 13 year old for school. Being the local `nerd' I got tagged with `picking out a good one' for her. Casio MS115: Scientific [no graphing]. This calculator is cursed by having its documentation not written by a native U.S. English user.
