I may have been a little quick to call bad on some who are into this crazy math.

6174 is known as Kaprekar's constant after the Indian mathematician D. R. Kaprekar. This number is notable for the following rule:

- Take any four-digit number, using at least two different digits (leading zeros are allowed).
- Arrange the digits in descending and then in ascending order to get two four-digit numbers, adding leading zeros if necessary.
- Subtract the smaller number from the bigger number.
- Go back to step 2 and repeat.
The above process, known as Kaprekar's routine, will always reach its fixed point, 6174, in at most 7 iterations. Once 6174 is reached, the process will continue yielding 7641 – 1467 = 6174. For example, choose 1495:

9541 – 1459 = 8082
8820 – 0288 = 8532
8532 – 2358 = 6174
7641 – 1467 = 6174

Is the principal understood?

Beats me. Look it up.

That is truly fascinating. Is there a mundane explanation?

I did the math wrong in my example, but something about it stuck out with the number i used like 598 or somethying, I will correct.
Or is 589 another example?

589 is a crypto meme, I didn't mean to confuse things.

I thinik I've heard of that.

1+2+3+4+5+6+7+8+9=45
1x2x3x4x5x6x7x8x9=326880
1x2x3x4x5x6x7x8x9x10x11=35956800
1089+911=1100
1x2x3x4x5x6x7x8x9x10x11x12x13x14x15x16x17x18x19x20x21x22x23x24x25=
1.551121004x10^25
pls excuse the tangent it just evokes a sense of wonder for me sometimes.

This what I have heard of 539, perhaps different than what you're talking about.

1089x9=9801

XRP to $589.
