This book presents a combination of an exercise book and practical guide to the CASIO fx-991 ES Hand Calculator. The basis of this book consists of ten assignments for the user, whose solutions can be easily understood and directly accomplished with the calculator.
An absolute innovation is the "table of contents" at the beginning of each chapter. There, the contents of the corresponding chapters are presented at a glance. In one part, there is the "problem statement", and adjacently, the overview for using the calculator.
