Section 2: Equations and Equality

No new computer skills are needed for this section, but you will need the book Thinking Mathematically. If you do not have Thinking Mathematically, but you do have the book Childrens Mathematics then you can skip ahead to the next section, and come back to this section when your copy of the book arrives.

If you have neither book, send me an e-mail to let me know that you will be delayed in working on this class until your books arrive.
