top! enlightening, motivating, complete

This is a good book astonishment of work, which fully realizes its goal to present and clearly explain the conceptual and technical refinements (or "know-how") of the first Math S program, chapter by chapter, in a powerful and understandable style. I think it is an excellent complement to classroom lessons, and all the other books courses and exercises.
The book is rich in diagrams, tables, graphs and equations, mostly legible and understandable and largely added remarks and comments in boxes.
Some passages appear a bit dense and clutter, so sometimes requiring an effort to review and synthesis.
The book does not present any major type of synthesis exercises "problem", but it is heavily typical exercises, and thus truly offers something to work.
The style is unique to the author, with a logical flow promoting better understanding, and touches of humor.
I thoroughly recommend it to any student who will take the time to deepen her during Maths, to mathematicians and parents should be much better help their children and even teachers (especially students giving private lessons).
