Anything special about the number 9?

Yes....The thing that is special about the #9 is that..........If you flip it it becomes a 6......and.......it's a composite number......which means it can be equally divided into numbers other than 1 and itself.....That other number is 3.

ALSO...

If you keep adding up all the digits of any of the multiples of 9 (including their intermediate sums) - they eventually add up to 9.


Examples:
18 breaks down to: 1 + 8 which adds up to 9 or
27 breaks down to: 2 + 7 which adds up to 9 or
5110092 (which is 9 x 567788) breaks down to: 5+1+1+0+0+9+2 adds up to 18, which breaks down into 1 + 8, which adds up to 18 which adds up to (guess what!) 9.


Try it yourself with any multiple of 9!
