Summary: Not Any Good If You Aren't An Expert In Algebra
Review: I bought this book to explain in simple language how to use the functions of the TI-30 I bought. The book gives you equations to plug in, but absolutely no explanation as to why the equations are set up as they are. It is totally useless for a person to buy this and try to learn on their own without the the aid of a teacher to explain the construction of the algebraic expression. After reading for 4 hours I was disappointed and will look for another book. It does show some neat graphs that the owner's manual doesn't get into, but if don't know how to create the equation it's a useless tool.
