PC
pc is a simple calculator program that uses arguments(or flags). It's useful to use with pipes and waste less time than using a interactive input calculator like using python or bc for example.
Diferences
It uses arguments, so for e.g., you don't waste time wainting interactive craps. All you need to do is passing the operation command and two more numbers.
