This is just a quirky function of our base10 number system. It happens in any placevalue notation of base n for the multiples of n1.
Also, if you take the digits of multiples of n1 and add them together, and add the digits of the result together, and keep adding digits until you have a 1digit number, it will be n1.
Eg. In a decimal notation, n1 is 9. 9x3=27, 2+7=9 9x11=99, 9+9=18, 1+8=9 9x987=8,883, 8+8+8+3=27, 2+7=9
In a hexadecimal (base 16) notation, n1 is F (in hexadecimal; "15" in decimal). Fx3=2D, 2+D=F Fx11=FF, F+F=1E, 1+E=F ("11" in hexadecimal is decimal "17") Fx3DB=3,9D5, 3+9+D+5=1E, 1+E=F
In binary (base 2), n1 is 1. So this works for any number at all. 10, 1+0=1 11,010,101; 1+1+0+1+0+1+0+1=101, 1+0+1=10, 1+0=1. etc.

I found this clock online, which has each number expressed with 3 nines: Not surprisingly, there were idiots getting into the whole 0.999... (repeating) = 1 debate, because it uses that to mark Seven. Again, there's no debate. When the nines are going off to infinity, the value is exactly equal to 1. A lot of the people who were debating otherwise were, also not surprisingly, computer programmers. They're an example of people who erroneously think of "infinity" as actual number. It isn't. There is no "last" or "infinities" place in the decimal. Fortunately there were others setting them straight. Regardless, I think it's a cool clock.

Also, if you take the digits of multiples of n1 and add them together, and add the digits of the result together, and keep adding digits until you have a 1digit number, it will be n1. Speaking of modulus arithmetic, in numerology there's the common practice of adding up the numbers corresponding to a person's name, then adding the digits of the result together, and repeating until you wind up with a single digit. Mystics still go through all of this, when all they really have to do is just divide the original number by 9 and take the remainder (or if it's 0, set the result to 9). But...don't tell them that! Multiples of 9 are also the underlying reason why this old online mindreading trick works: http://www.bored.com/mysticalball/index.htm

And now, for some REALLY misleading math with the number 9:

And now, for some REALLY misleading math with the number 9:
I believe that they can get in trouble from the Dept. of Weights and Measures for that sign. If the original price was $29.99 and they are saving $9, then the item would cost $38.99 not $39.98. That is a $300 fine by the DofW&M in San Bernardino County. They better fix it quick.
