General patterns	Specific details
We need to know that a cake has ingredients	We don't need to know what those ingredients are
We need to know that each ingredient has a specified quantity	We don’t need to know what that quantity is
We need to know that each cake needs a specified time to bake	We don't need to know how long the time is
