What is CALX?

CALX is an RPN calculator — a calculator designed to work with a list of numbers.

This means that instead of just typing an equation into your calculator, you push numbers onto a stack, and then apply operations to the lowermost numbers in the stack.

It's bizarre, but it makes sense once it clicks.

How you use CALX is up to you.
