Delving Deeper
Delving Deeper: More on Powers of m, Phone Trees, Symbolic Algebra, and Combinations

Linrong Zhang, Ying Wang 

September 2007, Volume 101, Issue 2, Page 150

Abstract:
This month, the authors respond to a MT challenge to bridge the gap between formal algebra and combinatorics. The authors explore connections between powers of two, phone trees, and symbolic  algebra and combinations. The "Delving Deeper" department provides a forum that allows classroom teachers to share the mathematics from their work with students, their classroom investigations and projects, and their other experiences. Edited by Al Cuoco and E. Paul Goldenberg.
