Implementing a Reverse Polish notation calculator in Ruby

A couple weeks ago I had a go at implementing an RPN calculator in Ruby. I knew I wanted the calculator to function by popping operands out of an array populated with the values of the input expression, operating upon the operands with the appropriate operator, and pushing the result back into the stack of operands.

I was able to implement this in version 1, but it took forever and the resulting code was not very beautiful. Why?

• I started coding before I had a thorough understanding of RPN

  Wait, 20 10 5 4 + * - is what now?

  # this creates a new, empty hash with no keys, but makes all default values zero. it will be used to store
  # the information from the array, such that the keys will be each unique number from the array (IOW, if there
  # are two or more 4's in the array, there will just be one key that is a 4), and the value for each key will
  # be the number of times that integer appears in the array.
  array.each do |i|
    counter[i] += 1

  # this interates throught the array, and for each element it creates a key for that integer (if it hasn't been
