Chapter 1 - Muddiest Points

The first chapter in our textbook is jam packed with lots of math ideas and concepts.  What ideas are you still trying to understand?  Sometimes knowing what you DO understand will help you narrow down what you do NOT understand.  So tell me what you know, and what you still have questions about.  Please post a blog within three days before our chapter 1 test, and we can talk about your questions in class.
