I was stunned at German math

When my kids finally started going to school in Berlin, I learned something I had always suspected: Germans can do witchcraft. They are experts in the black arts and can summon the spirits any time numbers are involved. When I sat down to help my kids with their math homework, my world changed. Inexorably. Forever.

It was so earth-shattering that I can’t even put it into words. So I made a video.
