What I Learned This Week

This week I learned lots of fun things about math. First I learned about inequalities and set notations.  We learned how to express inequalities and write them in interval notation.  Also I learned to use the Sign Chart Method which is

1. Make the inequality with a zero on one side
2. Factor
3. Mark where factors are zero
4. In each interval determine the sign

I also learned about absolute value and its properties and I learned about the rectangular coordinate system and how to graph with inequalities. Lastly I I learned and circles and graphs, the equation of a circle, semi circles and symmetry. Here is a picture of my notes....
