Title: Out of Date - Don't Buy
Review: It looks like this book was written in 2004. I just bought a TI-84 in September 2012 and apparently a lot of changes have been made by Texas Instruments in the intervening years.The first two things I tried to do for my math class had wrong instructions in the book. Most egregious is that the book tells you that there are two geometry applications. The book blows off one and focuses on the other one. Unfortunatly, the TI now only has the one not covered by the book.
Is the review positive or negative?
