This video tutorial explains when and why the inequality sign changes in mathematical expressions. It covers the effects of adding, subtracting, multiplying, and dividing both positive and negative numbers on inequalities. The key rule is that the inequality sign remains the same when adding, subtracting, multiplying, or dividing by a positive number, but flips when multiplying or dividing by a negative number. The tutorial provides examples to illustrate these concepts and concludes with a summary of the rules.
