Lesson Description:
This lesson consists of providing you with a Self-Tutorial on the basics of equalities and inequalities. I go over how to write results in interval notation, inequality notation, and set (set-builder) notation. I also explain in the printed notes how to use your graphing calculator to help you make comparisons between numbers.

Staff Review
A great lesson for any students learning about inequalities and the number line. This lesson also touches on set notation when describing inequalities. This is NOT just for beginner students. -
