I saw a lot of use of Roman numerals on buildings on my trip through Europe.

Spoiler.

I also used to have a clock that used Roman numerals.

I always mix up D & L, but otherwise I can read Roman numerals easily.
My math-history professor in college made us add, subtract, & multiply in Roman numerals once. Multiplication took forever.

And remember, "I'm-a Luigi, number one!"

I know them-----------high school Latin teacher insisted we use Roman numerals wherever possible.

I learned them. They become impractical after a point. Only time I commonly expect to see them is video game sequels, which I first started seeing probably in late 1991.
