## A Coherent Algebra Framework

Hung-Hsi Wu, a professor of mathematics at UC Berkeley, discusses the importance of seeing algebra as a whole rather than a collection of isolated facts and shortcuts to be memorized. He goes on to state the topics that would make up a coherent algebra framework as supported by the National Math Advisory Panel.
