The English word "four" has 4 letters. Are there any other numbers where the English name for them has that many letters?

The answer to your question is zero yet at this he same time zero is not an answer to your question.

-9 (minus nine) kind of works if we’re getting desperate.

  Sorry but whenever I see this symbols only thing I can think of CFT(d-orbital splitting). Because one time I asked my friend about CFT he used this symbols.

No. As a matter of fact, this is a neat party trick I used to use.

Start with literally any number, and count the letters to match it. You will always end up at four because it’s the only English word and Arabic numeral represented with equivalent letters.

All of them except one, two, six and ten have 4 letters. Most have more than that, but they also have 4. 😁

Remind me of the classic sequence where every number leads to 4.

10 -> 3 -> 5 -> 4

1024 -> 21 -> 9 -> 4

  Oh! Now I understand what that other commenter was talking about by ‘matching of letters to the numbers’ or something along those lines.

BananaTrifleViolin@lemmy.world ⁨1⁩ ⁨year⁩ ago
Yes: Five has four letters. Nine has four letters.

There are no more.

If you meant to ask if there are any more whole numbers with the same number of letters in the name as the number, then the answer is no. It is fairly simple to check - you only have to look at the numbers 0-30 before it becomes clear no other number will fit this pattern.

If you went into fractions like 20.12325 then there will be many numbers where all the letters added would get close but the fraction itself would mean you couldn’t quite reach the exact number as you can’t have fractions of letters.

If you included negative numbers then “minus eleven” has 11 letters. Minus thirteen has 13 letters. It seems to again break down once you go beyond 13, and its dodgy to include negative numbers as you can’t have negative letters.

So, no.

  Sigh. Time to introduce real letters that can be negative and fractional.

  To your first point: zero also has four letters.

I was able to come up with a list of similar scenarios for various languages using a simple formula in LibreOffice Calc: =LEN(A2)=ROW(A2)-1 (row 1 being a header row)

Language	Word	Digit
English	Four	4
German	Vier	4
Italian	Tre	3
Spanish	Cinco	5
Dutch	Vier	4
Portuguese	Cinco	5
Swedish	Tre	3
Swedish	Fyra	4
Danish	To	2
Danish	Tre	3
Danish	Fire	4
Norwegian	To	2
Norwegian	Tre	3
Norwegian	Fire	4
Finnish	Viisi	5
Turkish	Dört	4

In Hungarian, it’s “négy”, but it’s actually only three letters, n, é and gy.

I think the answer is no. It would only be possible with very small numbers. Even by the time you’ve reached 100, it’s not going to happen again.
