[iPad] How to get downloaded apps onto homepage?

 

I paid for and downloaded an app from the app store. However, it doesn't show up on the page with the other apps. Hunting for it seems to take me back to the web page where I downloaded it, rather than to the app I downloaded. That makes it very difficult to use. How do I get the downloaded app to show up on the 'home page' with the apps that came with the iPad since I don't see any way to have both that page and the page showing the app from the store open at the same time? Thanks.
