Acrostic Poem

An acrostic poem uses the letters in a topic, to begin each line. All lines of the poem should relate to or describe the poem :)-this is a smiley btw (i think this site should invest more on better looking emoticons.) 

that's better, now back to main topic, an acrostic poem is actually interesting. An example:

The Colour Of Peace
By Paul McCann
Pray for understanding to come
Each time and for everyone
An end to the hostility
Coloured as one in fragility
Enter compatibility
----I tried one out myself----
Lily
by Lilian
Lovely and adorable is the flower
I marvel at its beauty day long
Looks delicate and feeble
Yet its brightening bliss is perishable

Not as good as Paul's but i gave it a shot. You can check out this link in case you want to make one too for fun:   www.readwritethink.org/files/resources/interactives/acrostic/

Autobiographical number

Yeah sounds weird doesn't it...

It is a number with ten digits or less with the first digit (from the left) indicating the number of zeros it contains, the second digit the number of ones, the third digit the number of twos and bla bla bla...

One would think...well if its a number with a maximum of 10 digits, well we can have a large number of autobiographical numbers. NO! there are only 7 of them. Now, you could try finding which ones they are. I mean..7 only and you have the clues of how the digits in an autobiographical number are arranged. How hard can it be??

I'll give you the smallest and the largest autobiographical numbers as a sort of clue

The smallest autobiographical number is 1210 and the largest, 6210001000

:)

good luck!
