Calculators are too often regarded as devices to produce answers
to numerical questions. However, a graphics calculator like the
Casio CFX-9850GB PLUS is much more than a tool for producing
answers. It is a tool for exploring mathematical ideas, and we
have written this book to offer some suggestions of how to make
good use it when exploring ideas related to algebra. We assume
that you will read this book with the calculator by your side,
and use it as you read. Unlike some mathematics books, in which
there are many exercises of various kinds to complete, this one
contains only a few ‘interactions’ and even less
‘investigations’. The learning journey that we have in mind for
this book assumes that you will complete all the interactions,
rather than only some. The investigations will give you a chance
to do some exploring of your own
