class Point
  def +(other)
    #there your code, i think
    result = Point.new
    result.x = self.x + other.x
    result.y = self.y + other.y
    result.z = self.z + other.z
    return result
  end
end

but you also need to make the variables accessable like
class Point
  attr_accessor :x,:y,:z
end

and you should remove your init, it is wrong
