Mistaken

Michael Colpetzer, Amazon
12 January 2014
  • 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. I am very happy with this purchase.

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). I was so excited to get an affordable RPN calculator and I deflated like the Hindenburg when I figured out I got rooked.

HP 9G: A very sorry excuse for an HP graphing or scientific calculator

Ann E. Revelle, Amazon
28 December 2009
  • Summary: I purchased this unit with some high hopes directly from HP a few years back. At that time it was on on sale far below Amazon's going price range. I believe it was priced so low because 1) they/HP had way too many of these units in stock and 2) because a decision had consiously been made by upper level HP management to get rid of this entire line of Algebraic-only type calculators (like the HP30s, etc.).

All you need in a 1-line scientific calculator

E. Angie Neer, Amazon
12 August 2007
  • Summary: After many years of relying on my HP graphing calculators (48SX), I had to scale down to a one-line calculator for use in one of my exams. HP sets the standard for engineering calculators. Unfortunately, the graphing calculators are a little too powerful for use in certain exams, since you can almost program them to do the work for you. My professor specified "1 line calculator ONLY" for the final exam.

EXCELENTE PRECIO POR CALCULADORA

  • Summary: Una calculadora económica, ligera, aunque un poco difícil de manejar. Comparé precios y encontré que para ser una calculadora gráfica era la mejor opción. Recomiendo esta compra.
