This video is an overview of some of the basic operations in geometric algebra. It covers operations like the geometric, outer, regressive, and inner products, some of the involutions, and a few other operations. It also tries to describe these operations in a way that applies to arbitrary flavors of geometric algebra, to allow for a smoother transition into these other flavors.
In case you don't really know anything about geometric algebra, I would suggest watching my introduction to it first: https://www.youtube.com/watch?v=60z_hpEAtD8
I also have an important addendum that I made to that video as well: https://www.youtube.com/watch?v=0bOiy0HVMqA. This video assumes that you have a basic understanding of vanilla geometric algebra already, which you would get from these videos.
