Calc is a powerful programmable scientific, statistical and financial graphic calculator with 19 digits of decimal precision and over 200 functions including complex arithmetic, matrix and vector calculations , date arithmetic and unit conversions.

Calc  works like the classic HP calculators using RPN (Reverse Polish Notation).  There is definitely a learning curve to using a RPG calculator, you will probably need to study the extensive manual to be able to make any sense out of this calculator.

The keys work as described in the manual with one exception: The center OK key doesn’t work, you need to use the green Call key instead:
