In this new section on Inequalities, our instructor first guides you through the use of Addition and Subtraction Techniques to solve inequalities. After a summary of the fundamental principle, you will learn about three ways of representing inequalities: inequality notation, set builder notation, or as a graph on a number line.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
