*Mathematica* is a powerful system for doing mathematics on a computer. It has an inbuilt programming language ideal for extending its capabilities to mathematical systems like Grassmann algebra. It also has a sophisticated mathematical typesetting capability which retains its computational attributes. The Grassmann Algebra book uses both. The chapters are typeset by *Mathematica* in its standard notebook format, making the book interactive in its electronic version with the *GrassmannAlgebra* package. *GrassmannAlgebra* can turn an exploration requiring days by hand into one requiring just minutes of computing time.

*Mathematica* is available for most operating systems.

To use the *GrassmannAlgebra* package you will need *Mathematica*. If you just want to read the book, you can download it as a .pdf.
