Net run rate
As an example, if a team wins a game 300 runs to 200, with it having batted 200 legal deliveries (33.2 overs, meaning 33 overs and 2 deliveries, or 33 overs plus a third of an over) and its opponents having batted 185 legal deliveries (30.5 overs), then the team's Net Run Rate during that game is (6*((300/200)-(200/185)))= 2.51.
