In this video we talk about how to find the cross product of two 3 dimensional vectors by hand. If you're doing multivariable or vector calculus, you're going to be doing a lot of cross products, many--if not most or even all!--by hand. We talk it through and then do two examples. In the first I show all the work, in the second I show how I end up doing them "in my head" most of the time.
