The video tutorial covers compound inequalities, focusing on the intersection and union of sets. It explains how to express these inequalities graphically and using interval notation. The tutorial provides examples of compound inequalities connected by 'and' (conjunction) and 'or' (disjunction), illustrating how to graph them and write their interval notation. It also addresses more complex inequalities that require solving for variables, emphasizing the importance of understanding the mathematical meanings of 'and' and 'or'.
