of course you don't.
it's just illustrating why math is useless beyond the basics. this is something that every 6th grader figures out on their own but is then lectured by math nerds on how wrong they are. the same sorts of people who insist that we'll leave the solar system sometime in the next 34093840348 years because of math.
the same people who design doors on a tesla that can't be opened in normal circumstances and roast passengers in raging infernos.
that's all math, and none of it it funny unless you're laughing at math.
