Because you are calling puts with the result of the each method, which
in this is the range.
Take into account that .each will run the block yielding each element,
and then will return something.
You can remove the last puts:

def dial(digit)
  puts digit
end
digits = 0..9
digits.each {|digit| dial(digit) }
