While this is seemingly simple, the use of metrics is rather powerful. You can add metrics to a report by dragging the appropriate metric to the metrics section of a table. You can also break down dimensions by metrics, giving you fine-grained control over the table view.

The possibilities are endless.
Or you can click Components > New Metric. This will take you to the Calculated Metric Builder, where you can build custom metrics from existing metrics.
