Read in the Mail letters, if you add the last 2 numbers of a persons year of birth and the age they will be this year it comes to 111 :o and it does :o but how? I'v done it to everyone I can think of, it's driving me crazy.
and yes I know I have too much time on my hands at the mo ;D

I thought it didn't work for my daughter until I remembered how old she actually is going to be this year!! ;D ;D ;D
So, what's the mathematical explanation someone clever out there? ???

It does seem very strange ;D
It only works for people born after 1899 and before 2000 :D
Next year, the same trick will give the answer 112. Last year it would have been 110.
If you add a person's age this year to the year in which they were born, you get the current year, ie 2011.
If you just take the last 2 digits of the year they were born, you are removing 1900.
So 82 instead of 1982, 54 instead of 1954 and so on.
Take 1900 away from 2011 and you get 111.
If you were born in 1899, the answer would be 211. For anyone born this century, the answer is 11
So who was the idiot person who thought it up to start with?

its as clear as mud !!
It's not that odd really.
Take the year you were born, add the number of years since then, and you get the current year.
It's 111 because you're counting years since 1900, and on that basis the current year 111 rather than 2011.

I think you're looking for complications. There isn't a trick.
It's no different from working out someone's age from their date of birth
it;s a quirk of having a counting system based on units, tens, hundreds.......

Not one different and it goes for their grandad who was born in 1926.
