Nah, it the stuff that the dental hygienist scrapes off your teeth.

Tip: dx(2x³) = 6x

Here is a great read about math in American schools: Why do Americans Stink at Math?

If only time went into teaching instead of turning it into a game/memorisation...

Interesting article. Maybe all these years I have been too hard on myself, maybe it was how math was taught that create the issues with it. Seems to be a more widespread issue then I ever thought.
