### 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.
