Social Security Numbers' Mystery Unmasked

We all know that a social security number is made up of the “Area number”, the “Group number” and the “Serial number” (AAA-GG-SSSS), but did you know there is a mathematical formula behind them that proves Chaos Theory? Try this out, I promise it works. That and I have way too much fucking time on my hands.

If you take the sum of the first three digits, plus the sum of the second two digits, minus the sum of the last four digits, multiplied by the three digit number created by the first, fourth and seventh digits, then divided by difference between the first and last digits given the last is larger (difference between second and eighth if this is the case) then if the middle two digits are less than 50 you round the number to the tenth, if the middle two digits are more than 50 you round the number to the hundredth, if the middle two digits are equal to 50 you round to the whole.

Take that final number and multiply it by sixth digit, minus the seventh digit, divided by the eighth digit and add the ninth. Square the number. Write that number down, we’ll come back to it.

Add each of the individual numbers together, subtract your birthdate, subtract the year of your birth (ie subtract 1,975 if you were born in 1975) and add the number of siblings you have (only those born before you). If this number is a positive number, take the square root and round to the nearest whole number. If it is a negative number, subtract it from itself (ie, if -1985, subtract -1985 from it.). Multiply this number by the number you have wrote down from the last part.

This final number is the amount of you I expect actually mathematically finished this equation. Especially on a friday night.
