How to recover accidentally deleted iOS10 native applications

For some native iOS 10 applications that are barely used, you can click the application icon in the upper left corner to delete them. If you want to retrieve the deleted application, how can this problem be solved?

Method 1: restore the home screen layout

In [Settings]-[general]-[restore], select [restore home screen layout] to restore the original screen layout, however, the disadvantage is that the current home screen layout will be disrupted.

Method 2: Download from App Store

In the iOS10 system, some applications can be downloaded in [App Store], but some applications cannot be searched. Therefore, when searching for an application in App Store, please output the calculator name (calculator) to search for and download.

(Do not make the app wrong. The publisher of the official calculator is Apple !)

Method 3: Take the calculator as an example. Open Siri and say "calculator" to Siri. In the response content of Siri, click [App Store] to directly jump to the download page of the app, download directly.
