Actualym, the book was intended as a gift. If it were for me I would have to given it much lower rating -- since I am from the old school and the symbology had some logic behind it this make little sense unless I took the time to converty all that I know then start from scratch.. It appears that all of the newer math books are copies of others work with just differenmt symbology -- more to confuse and not to standardise. Seems the Hypotenuse, adjacent, and opposite are no longer in vogue. The new make things up as they go along, then with its Mediocrity , it becomes a standard. Too bad, we have to continually be confused. No sense, no logic, no worry how it affects out fellow man.

But, since the person had no previous background, they did not notice any differences -- so they thought they would find good use for it.

As usual Schaum is a pretty good reference and representative book.
