I've only read a few but its hit-or-miss... to be expected since the series is written by so many different authors. I think the Manga Guide to Databases was really good, but the Manga Guide to Linear Algebra was pretty bad. To be fair, Linear Algebra is really difficult to teach and hard to think of a silly story to wrap it together. But the Princess in the "Database" story is trying to organize the apple-orders of her kingdom, and that's just enough "story" needed to be a good, practical example of Databases, 3rd normal form (as well as the inconsistencies you'd come across in just 1st or 2nd normal form... and how those inconsistencies could lead to double-orders or incorrect data).
