Collection of Lame Jokes

[fresh_42]

I won a bet against someone, that they could multiply any numbers of length 2 ( contrived, but necessary*) in less than 3 minutes.

I proposed LX times CI .

*Needed to avoid talk about digits, since Roman numbers have no digits , at least in the sense of standard Decimal ones.

Easier than DF times A5.

Or Z_n , when n>26, so you've run out of letters of the alphabet.

Mathematicians know only five numbers: $-2\, , \,-1\, , \,0\, , \,1\, , \,2.$ $3$ is already $n$. And it is more than just a joke. There is a subtle change between two and three. E.g. the tensor rank (minimal number of generic tensors) is easy for two, but it starts to become quite difficult for three and higher degrees.

There was a film short (from Dust?) a little while ago about a guy who discovered a secret integer hiding between 3 and 4. No one believed him until after he died and one man saw a collection of four objects on a table, picked one up, and looked back down and noticed that there were still four objects on the table!

There are two there: $\pi$ and the sum of all reciprocal Fibonacci numbers.

There's a Greg Egan short story with a related premise. It turns out that the rules of arithmetic aren't completely settled for very large numbers, and somebody manipulates that so that temporarily the rules aren't completely settled for small numbers either, leading to a situation where three groups of two objects and two groups of three objects don't have the same number of objects.

OMG!! That's the reason they won't teach commutativity of multiplication in the US school system anymore! I never understood why.

It was hard to watch, but I love that episode.

Essentially the same joke:

My uncle died peacefully in his sleep.

Unlike his passengers.

My uncle died peacefully in his sleep.

Unlike his passengers.

The version I heard was: When I die, I want to go peacefully, in my sleep, like my uncle. Not all screaming and terrified like his passengers.

But, to be fair, I believe that, technically, the gestation time for an Osprey is more like 3 years.

VMLXAccording to:
https://byjus.com/maths/roman-numerals/

. When a symbol of a smaller value appears before a greater value symbol, it will be subtracted. For Example- IX = X – I = 10 – 1 = 9.

. The symbols V, L, and D are never subtracted, as they are not written before a greater value symbol.

I have not been able to find any information that the Romans depicted numbers as products of numerals. Please let us know if you find such.

Cheers,
Tom

Please quote correctly! I wrote $\overline{V}MLX$!

That's why I used the overlined symbol. $\overline{V}=MMMMM>M.$

There are various ways to deal with numbers greater than a thousand. Overlining is one of them.
