Multiply this number by 2.
Add 5.
Multiply it by 50.
If you have already had your birthday this year add 1755. If you haven't, add 1754.
Now subtract the four digit year that you were born.
Have a 3 digit number? The first digit of this was your original number. The next two numbers are your age! This is the only year (2005) that this will ever work.. so spread it around while it lasts!
