Get Virtual HP15C Calculator

Yves, Amazon
22 September 2014
  • Summary: Great calculator for less than $20 at iTunes store. Get virtual calculator for use on phone and tablet and save lots of money. Have had physical HP 12C calculators for over 25 years (and they all still work). Please be careful of price gouging, as the calculators should be about $100 for a physical calculator.

  • Summary: The 15C is the best scientific calculator HP ever made. I've had mine for about 30 years and I still use it daily. I have a 48G, but I never use it.

Doesn't calculate sin correctly!

tillie, Amazon
19 August 2014
  • Summary: I am a true fan of the HP 15C (the original). However, when I tried to calculate sin(45), it gives me the answer as if I were calculating it in radians, not degrees. I tried to convert to degrees, the display indicates I am not in radians, but the answer is still 0.8509 instead of 0.7071. I just wonder how many other functions operate incorrectly. Thankfully, I remembered sin(45) from 30 years ago in college so I caught it.

HP-15C is a Great Calculator, solidly built and easy to use in your hands.

chris1guy, Ebay

  • Summary: This is the ultimate 10 series calculator from HP. It is so good and popular that HP did a special edition re-manufacture years after it went out of production. The original HP 15C is heavier, solidly constructed and lasts. The "landscape" orientation allows for two thumb operation while holding it in your hands. RPN makes for really fast calculations without brackets or an equals sign.

It is like a "Linus blanket" (Charlie Brown reference)

John P., Amazon
19 June 2014
  • Summary: I am lucky to have hidden my original 1980's HP 15C ,from the ex wife on a cleaning out the house weekend whim. I recently pulled it off the bench and put it back into the game. I decide to go back to academia at a latter point in my life. I am the oldest in the class. Most of the others have bloated function graphing calculators, but with RPN I am able to come up with results fast enough to seam omniscient to others.

Beware the quality

weberpxw, Amazon
16 May 2014
  • Summary: I totally LOVE the HP15C model, and when my original calculator failed after decades of use I was happy to see it reissued in the "Limited Edition." HOWEVER, I am finding that the key strokes on the version (made in China) sometimes (a) do not register, or (b) "bounce" so as to effectively be registered twice.
