Leave a Review MathU RPN Calc
Love this calculator!
This is my daily go-to calculator. It's also my absolute favorite HP emulator! It does everything I need from a calculator. Great combination of functions! Anyone who used the older vintage HPs will appreciate this calculator. Thank you Dr. Thompson for keeping this app current!Awesome calculator!
I use this calculator on a daily basis and absolutely love it. I have been a fan of HP calculators since the 80’s and glad I found this app a number of years ago.Superb
I’ve used RPN since my first HP calculator 50 years ago. This app is a superb duplication of the original and looks just like the original keyboard. Perfect for all my scientific needs.
