Some New Videos

There are certain topics that really interest me when teaching different math classes.  Recently my Algebra 2 class was working on some absolute value equations and inequalities and I made a couple of videos on the topic.  I thoroughly enjoy teaching the students this topic. The first video explains how to turn an absolute value equation into a piece-wise function:
The second and third video are a couple of examples.  The examples are $$|x+5|-|x-2|=8$$ and $$|3x-2|+2x=8.$$  There are certainly other methods for solving these problems, but creating a piece-wise function is effective and also useful when trying to graph functions of a similar nature.
