Preface A note on the print version

This book aims to develop readers’ ability to reason about linear algebraic concepts and to apply that reasoning in a computational environment. In particular, Sage is introduced as a platform for performing many linear algebraic computations since it is freely available and its syntax mirrors common mathematical notation.

Print readers may access Python online using either Google Colab

or an online Python interpreter such as Online Python.

Throughout the book, Python cells appear in various places to encourage readers to use Python to complete some relevant computation. In the print version, these may appear with some pre-populated code, such as the one below, that you will want to copy into an online Python cell.

We’ll talk more about the Python code in that cell in later sections of the textbook. For now, note that you can run the code, make changes, and experiment directly within the text. Sometimes we’ll share empty cells, like the one below, which are generally intended to indicate that part of an exercise or activity that is meant to be completed with Python.
