numbersNovember 11 is my youngest daughter’s birthday. In looking around for something of interest related to birthdays I found the following. It works, try it.

Mathematicians have devised a simple formula linking your social security number’s first digit and your age, and the startling connection holds only for this year.

Check it out yourself by doing the following elementary calculations. a.) What is the first digit of your social security number. b.) Multiply this number by 2. c.) Add 5. d.) Multiply it by 50. e.) If you have already had your birthday this year add 1759, and if you haven’t, add 1758. f.) Now subtract the four-digit year that you were born.

You should have a three-digit number whose first digit should be the first digit of your social security number, and whose next two digits are your age. And, as mentioned, 2009 is the only year this will ever work.
