That’s true, aggregates can now be used for things other than relationships! That feature was added super recently, and is still having the tyres kicked (so to speak), and it’s a bit too late to update the book with this new info ☹

As for calculations, we do go into examples first on how they can be used for generally calculating things, like the `years_ago` that an album was released. We use them more in later chapters for things like the track number of an album, and policy checking who can manage album data!
