Hey everyone,
Today, Lynette and Shao reminded me of a
very important fact.
-drumroll-
THERE ARE NINE MORE DAYS TO TOURNAMENT!NINE! As in:
- lynette's jersey no.
- kyuu (japanese)
- neun (german)
- neuf (french)
- εννέα (greek)
- nove (italian/protuguese)
- nueve (spanish)
- 九 (you had better know what language this is)
- 9 :)
JIAYOU EVERYBODY!
FYI:
9 (nine) is the natural number
following 8 and preceding 10. The ordinal adjective is ninth.
Nine is a composite number, its proper divisors being 1 and 3. It is 3 times 3 and hence the third square number. 9 is the first composite lucky number
(this is a good omen!).
Nine is the highest single-digit number in the decimal system.
There are nine Heegner numbers (don't ask me what they are. Google it if you're that interested).
A polygon with nine sides is called an enneagon (technically) or nonagon (in common usage). A group of nine of anything is called an ennead.
In base 10 a number is evenly divisible by nine if and only if its digital root is 9. That is, if you multiply nine by any natural number, and repeatedly add the digits of the answer until it is just one digit, you will end up with nine:
2 × 9 = 18 (1 + 8 = 9)
3 × 9 = 27 (2 + 7 = 9)
9 × 9 = 81 (8 + 1 = 9)
121 × 9 = 1089 (1 + 0 + 8 + 9 = 18; 1 + 8 = 9)
234 × 9 = 2106 (2 + 1 + 0 + 6 = 9)
578329 × 9 = 5204961 (5 + 2 + 0 + 4 + 9 + 6 + 1 = 27 (2 + 7 = 9))
And so on. Cool right?
(The only other number with this property is three.)
There's alot of interesting stuff on wikipedia. Seriously, I never expected such a long entry on the number 9. Well, now I know. :) Damn, I'm learning from shufeng with the wikipedia research and all. NOOO!
