Be sure you don't read the bottom until you've worked it out and no cheating please 'cause that would ruin it and it's good in a weirdy arithmetic kind of way.
First of all, pick the number of times a week that you would like to have chocolate more than once but less than 10 (any more than that and you're a pig, girlfriend)
Multiply this number by 2
Add 5 (for Sunday)
Multiply it by 50
If you have already had your birthday this year add 1751 and if you haven't, add 1750
Now subtract the four-digit year that you were born. You should be left with a three-digit number
The first digit of this was your original number (how many times you want to have chocolate each week) and the next two numbers are your age.
Like, how cool is that?
