new kind of interactive problem book released
I found a newly released problem book on intermediate and college algebra, with medium and advanced level problems. What it brings new is its structure: it does not only contain the problems and their solutions, but the solver passes through three intermediary stages to the final solution: hints, solving algorithms and proofs, which are separate in the book.

Sounds like a great system I wll go and have a look. For my childrens foundation math learning I used math board games and they worked very well.
