### Ancient Roman Numerals

def to_roman(integer, numeral="")
  return numeral if integer == 0

  if 	integer/1000 >= 1
    numeral << 'M' * ( integer/1000 )

###In Ruby, is the attribute of an object an object?

To illustrate, let's define a Book class where each book (or each instance of Book) has an author.

# The following method will take strings like '5 4 +', '-1', '5 -3 4 + 6 9 - * +', and '2 3 4 7 + * -', and return the result of running the calculation.
# Note: when performing division it will always round down.

def evaluate(string)
  return string.to_i unless string.include?(' ')
  string.match /(-?\d+) (-?\d+) ([-+*\/])(?!\d)/
  result = ($1.to_i).send($3,$2.to_i)
  string.gsub!($1 + ' ' + $2 + ' ' + $3, result.to_s)
  evaluate(string)
