This video teaches students how to multiply and divide to solve equations in algebra. The teacher made this video specifically for his class because he points out page numbers from the textbooks that the students can go back and review. He is standing in front of a dry-erase board explaining various examples. This video is intended for people who are very new to this concept because he progresses very slow through his examples and tends to repeat himself. I think this is great for students who are new to this video, but if you're familiar with it, then it could be boring and too long.
