# Introductory Linear Algebra

Some elementary knowledge of algebra is assumed. Unit 1 of the Algebra wikibook should be more than enough to learn these elementary knowledge. |

This book is part of a series on **Algebra:**

This book serves as a *mild introduction* to linear algebra, and is not too proof-heavy and proof-based.
Most topics covered are useful for applications in disciplines other than mathematics. Thus, this book is probably more suitable
for non-math majors. For math majors and people who want to study *proof-based* linear algebra, see Linear Algebra wikibook.
This book should *not* be a prerequisite of the Linear Algebra wikibook (but may help understanding it), despite similar topics are covered,
since the topics are discussed in quite a different way, and some definitions may differ.
