Sounds like you do need one. 63 mph = 169344 fpf.Ooops... so I multiplied by 63 when I should have divided into 63... Hey, it was close, only off by a factor of 7.2 million. Why, that's only six orders of magnitude.
It's nice to know that there's
someone out there checking up on my math!
I have applied for a job with the US Government, pricing out things like toilet seats and hammers.

Well, after this debacle, I better go practice my gazintas.
Adding and subracting is easy, multiplication a bit harder, but gazintas are hardest of all. You know -- like seven gazinta 63 nine times.
