This is a command line application that implements a reverse polish notation (RPN) calculator. RPN, also known as postfix notation, is is a mathematical notation in which operators follow their operands.
Ex. '3+3' is written as '3 3 +'
If there are multiple operations, operators are given immediately after their second operands.
Ex. The expression written '3 − 4 + 5' is written as '3 4 − 5 +'
4 is first subtracted from 3, then 5 is added to it.
The following table is a visual breakdown of the algorithm:

To use the calculator, run $ ruby/bin.rb.
Currently, the application does not contain any tests. Future implementations include testing to ensure proper functionality and output of the application.
