The Equations and Inequalities: The Operation on the Inequalities

The video tutorial explains how to handle inequalities when performing operations such as addition, subtraction, multiplication, and division. It emphasizes that adding or subtracting a constant from both sides of an inequality does not change the inequality's direction. However, multiplying or dividing by a negative number requires reversing the inequality sign. The tutorial includes examples to illustrate these concepts and concludes with practice problems to reinforce understanding.
