This book is of course much better than the horrible manual that comes w/the 89 (who were they kidding)...however, it could be MUCH better at showing how to imput expressions or equations. I am a math idiot...the TI89 has saved my butt (I just need to take Algebra even though I am a history major) but if you do not know EXACTLY how to enter say a radical then you are left hanging. The examples that are shown are good, but for much less complicated problems...not dealing w/indexes and exponents at the same time. Unless I've missed something. I've had to call TI tech support to teach me how to input various problems...and they were very helpful....now if they would only rewrite THEIR manual and not assume everyone is a math wizard.
