There is a “sex math” trick that floated around the internet back in the day… it can be found at these places:
The only problem is this trick ONLY works if the year is 2003. Basically, the trick goes like this:
First of all, pick the number of times a week that you would like to have sex ………
(try for more than once but less than 10)
Multiply this number by 2 (Just to be bold)
Add 5. (for Friday Night)
Multiply it by 50 (being a bit stupid)
I’ll wait while you get the calculator…………….
If you have already had your birthday this year add 1753….
If you haven’t, add 1752 ……….
Now subtract the four digit year that you were born.
(if you remember)
You should have a three digit number
The first digit of this was your original number
(i.e., how many times you want to have sex each week).
The next two numbers are your age.
IMPRESSIVE ISN’T IT?
But this sex math trick is a complete FAIL, hardly impressive I would say. You pick a single digit number x.
100x+2003 (or + 2002)
100x+2003 (or + 2002) – your birth year.
clear where the error is. If you do 2003 (or 2002 if you already had
your birthday) and subtract your birth year then you would get your age
in 2003. Thus, every year, the “add 1753” step needs to change to
adjust for which year it is. Obviously if you keep it at 1753 then the
trick won’t work in future years (like 2009).
