What are the Multi-Touch Gestures on the iPad?

Apple's iPad Tablets come with multi-touch gestures. These gestures allow you to perform multiple functions by simply sliding or moving your hands on the screen in a particular way. This makes performing tasks such as going back to the home screen faster and easier. You can also switch between apps, and open up the multitasking panel.

Use 4 or 5 fingers for all the gestures:

To go home- use all fingers and pinch in
To switch between apps- use the fingers and slide left or right
To open the multitasking try- use fingers and slide up
