Exploring Adding and Subtracting Rational Expressions

This video tutorial covers the basics of inequalities, including the use of inequality symbols, translating verbal statements into inequalities, determining solutions, and graphing inequalities on a number line. It explains the use of open and closed circles for graphing and provides examples to illustrate each concept.
