The video for this lesson only covers inequalities involving addition and subtraction. The problems given in the lesson include inequalities involving multiplication (so far).

One explanation for a problem said that when an inequality involves multiplication or division, you have to flip the arrow to face the opposite direction in your answer. Then I just did a problem in which the "Show Steps" did not list this as a step towards finding the solution and the arrow did not change direction.

This lesson needs more clarity in the instructional video.
