Ever tried to multiply longhand with the Roman numeral system? XVII x IX? *\;-)

Place value is great because it works with all sorts of systems: base-2 (binary), base-3 (trinary), base-8 (octal), base-16 (hexadecimal)...

"Ever tried to multiply longhand with the Roman numeral system? XVII x IX?"

That's why they invented Roman Logarithms.

All you have to do is look up the log of the first number, add it to the log of the second number, and then look up the anti-log.

The only problem was it wasn't accurate to any Decimal places.
