"To think recursively means to address a problem by assuming that similar problems of a smaller nature have already been solved and figuring out how to put those solutions together to solve the larger problem".
This text is from the book, "Discrete Mathematics", by Susanna Epps. It's really less a book about math, per se, than an effort to get its readers to think about how to solve problems.
I recommend it highly [you can find it free online, I did] for anyone to improve their problem solving skills [my motivation]. Solving problems leads to confidence; what could be more useful than that?
