# PrefaceVariants of this textbook

There are several variants of this textbook available.

- The master version is the default version of the book.
- The version for math 1553 is fine-tuned to contain only the material covered in Math 1553 at Georgia Tech.

The section numbering is consistent across versions. This explains why Section 6.3 does not exist in the Math 1553 version, for example.
