Aren't those operators at 1:40-ish actually called compound assignment operators, and not unary?

You're right. Looks like they changed this naming in Swift 3.0.1. I'll update the course. Thanks!!

And the video forgot to mention the unary '-' operator which changes the sign of a number. i.e.
var x = 3 let minusX = -x // = -3
