As a kid I stressed our Olivetti divisumma 24 ( https://www.ithistory.org/sites/default/files/hardware/Olive... ) with a million times a million. It entered a perpetual mechanical cycle that even unplugging it could not break. Finally Dad had to attack its innards and tug and twiddle until he pulled out a spring loaded gear and it caught a cog on the next go-round. It lifted its digit arms and printed out a 'partial answer' that was a series of random numbers as wide as the whole mechanism.

He said "please don't do that again." I moved on to torture computers.

I'm kinda wondering are there any countries that still use the long scale nowadays? For me the biggest thing I've had to learn is that in Russian we use a short scale, except we don't have "billion" and instead it's "milliard". So it's just that you need to be careful with translating that one word. Are there other countries where the scale "shifts"?
