When you copied Plus to Multiply what hotkey was that? Usually your videos do a helpful text overlay to show the hotkey that you’re using but there wasn’t an overlay for this one.

I’d also recommend switching to a more basic example because I wanted to figure out what the heck was going on with those free-floating new statements and ended up going to the source code and digging around to learn that it’s singleton based registration. Which is neat, but distracted from the main focus of the video: branching.
