What does the number on the Cluster mean?

How are the markers grouped in Google Maps?
But for the sake of clarity, this document will name them ‘markers’ throughout. When a user views the map at a high zoom level, the individual markers show on the map. When the user zooms out, the markers gather together into clusters, to make viewing the map easier.
