How do updates work

[paulbaker99]

If I buy a game or some other app and it gets updated how do I add the update to the game or program I already have

You update it through the App Store.

The App Store icon will show a small-font number in the corner when there are items waiting to be downloaded, including updates. It's not unusual for me to see "25" or "30" on my wife's iPad at any point because she doesn't do a lot of device management on her own.
