1) Think of a number, any number. Write that number down: ________ (EG: 4261)
2) Multiply the number by 9. Write that number down: _______ (EG: 4261 x 9 = 38349)
3) Add that number's digits across Write the result down: ______ (EG: 3+8+3+4+9 = 27)
4) Repeat step 3, until all the digits added across are less than 10. Write the result down: ____ (EG: 2+7 = 9)
You answer is always 9.
You can do a lot of mind games with this trick.
But you can use this trick to figure out REALLY quick, if a number is divisible by 9.
EG: For example
     123,456 = (1+2+3+4+5+6) is 21 = (1+2) is 3, which is not divisible by 9. 123456 / 9 = 13717.333333333334
     1,234,566 = (1+2+3+4+5+6+6) is 27 = (2+7) is 9, which is divisible by 9. 1234566 / 9 = 137174
Boring, I know, but it can be useful at times.
Every number seems to have its tricks.

STAY COOL!

If a packet hits a pocket on a socket on a port,
and the bus is interrupted  at a very last resort,
and the access of the memory makes your floppy disk abort,
then the socket packet pocket has an error to report.   
If your cursor finds a menu item followed by a dash,
and the double-clicking icon puts your window in the trash,
and your data is corrupted cause the index doesn't hash,
then your situation's hopeless and your system's gonna crash!
If the label on the cable on the table at your house,
says the network is connected to the button on your mouse,
but your packets want to tunnel to another protocol,
that's repeatedly rejected by the printer down the hall.   
And your screen is all distorted by the side effects of gauss,
so your icons in the window are as wavy as a souse;
then you may as well reboot and go out with a bang,
'cuz sure as I'm a poet, the sucker's gonna hang.   
When the copy on your floppy's getting sloppy in the disk,
and the macro code instructions is causing unnecessary risk,
then you'll have to flash the  memory
and you'll want to RAM your ROM,
and then quickly turn off the computer and be sure to tell your Mom!
