Inequalities and Operations Review

In this video, Miss V teaches how to solve two-step inequalities with rational numbers. The lesson builds on previous knowledge of one-step inequalities and emphasizes the importance of flipping the inequality symbol when multiplying or dividing by a negative number. Several examples are provided, including those involving fractions and negative numbers, to illustrate the process of solving these inequalities. The video concludes with a recommendation to watch related videos for further practice.
