4 and 44
Way back when I was a kid, my eldest brother used to subscribe to Reader's Digest and in one of it's annual 'gift' he once received a book on riddles and IQ tests. The tests fascinated me till this day.

I still remember the one test where you have to write arithmetic formula -- that is using addition, subtraction, multiplication and division only -- to represent the numbers 1 till 12 by using the 4 digits of the number 4. (Now you know why I studied mathematics..)

It started by giving the two examples for numbers 1 and 2 :

1 = 44/44 and 2 = 4/4 + 4/4. Now you try to figure out the rest. (I will post the answers in a day or two, ...i.e. when I myself got to figure out the answers...)

Why the sudden interest to write on the number 4??

The number 4 has always been my favorite number. It's easy to see why...

I was born on the 4th.

And today I am 44 years old.

And I am so blessed. Happy Birthday to me...
