This video tutorial covers solving absolute value inequalities, focusing on both 'less than' and 'greater than' cases. It explains how to handle these inequalities by converting them into compound inequalities, using 'and' for less than and 'or' for greater than. The tutorial includes examples for each type, demonstrating the process of solving, graphing, and writing solutions in interval notation. The video concludes with additional examples to reinforce the concepts.
