### Conclusion

I hope that you can see the contribution made by the study tour of China to my appreciation of the *Nine Chapters*. Although cultural context for the *Nine Chapters* was merely a small part of what we learned on the trip, we can now share it with our students and colleagues. I have found that it truly enriches the experience of my students in the history of mathematics.

### About the Author

Joel Haack is a professor of mathematics at the University of Northern Iowa, with mathematical interests that include the history of mathematics, algebra, probability and statistics, and the connections between mathematics and the arts and humanities. Joel and his wife Linda were frequent travelers with the MAA Mathematical Study Tours, having traveled with the group to Greece, England, Mexico, China, Russia, Switzerland, Germany, Ecuador, Guatemala, Honduras, and Italy. Returning to the faculty after 20 years in administration, Joel is pleased to be able to share what he learned on the MAA Study Tours with his students.
