So I don't know why I can't figure out the answer to this. I'm guessing it's how I'm asking it. My nikkor 18-55 has 1:3.5-5.6. Can someone explain why the two f stops?

18mm at f/3.5, 55mm at f/5.6. Variable Aperture because of the design of the Lens...............

Ok so it's based on the mm. I've really got to sit down and learn about lens structure and design
