Understanding Inequalities

Miss Wendell discusses inequalities, focusing on writing them using variables, signs, and numbers. She provides examples to illustrate how to determine if a solution works for an inequality, how to graph them, and how to interpret keywords like 'at least' and 'maximum'. The video concludes with a reminder to complete a book assignment on Google Classroom.
