So here's something I found that was interesting:
If you put a line over Roman Numerals, that number is multiplied by 1,000.
Roman Numeral IV is the number 4 but looks like an N, X is 10.
Normally you wouldn't be able to write IVX as a number, but with this tech, you can write IÌ…VÌ…X to represent 4,010. Why is that interesting? Because NX was what the Nintendo Switch was officially code named by nintendo before it was released. So, if you want to be a nerd like me, you can refer to the switch as 4,010.
