SOCS-I (Arons 3.16-3.24 ish)

I remember reading the entry on equal signs before (I have owned the Arons book for a few years now) and it struck me again how much the material that we find so simple can be so confusing to our students.  I have made a point to talk about the different meanings of the equal sign in my class, but taking this class has pointed out so many more places where I have to be careful not to gloss over material that can be totally confusing to my students.
