Fun with algebra mistakes

I really don’t know enough about math to know if this video, The Top Ten List of Algebra Mistakes, is for real or not, but whether these are real mistakes or not, this video is a great example of how to make fairly boring and mundane things a whole lot of fun. If you’re an algebra teacher and these are real mistakes, use this video in your class. If these aren’t real, well, why aren’t you making a video for real errors? Even learning the mundane can be fun. This is very cool.
