It has only a vague meaning. It means that I have yet to see an algebra book (beyond grammar school level) of the last 70 years where the author takes the pain of explaining how to transform equations in order to get them solved. Today the focus is on algebraic structures. The modern approach, as for instance in van der Waerden's book which originally had the title "Modern Algebra" and later "Algebra" is, of course, in general much more fruitful for mathematics, but if someone has an equation and wants to find its solutions, he may be better off with an old book.
