This is pretty neat so please don’t cheat by scrolling down first!
It will take you less than a minute and is fun (especially for chocoholics).
Work it out as you go along.  Calculators are allowed!


1. First of all, pick the number of times a week that you would like to have chocolate (more than once but less than 10)


2. Multiply this number by 2


3. Add 5


4. Multiply it by 50 — I’ll wait while you get the calculator


5. If you have already had your birthday this year add 1759 and if you haven’t , add 1758


6. Now subtract the four digit year that you were born


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 chocolate each week).

The next two numbers are…

  1. After seeing all these scrumptious pics I had to add another number… :) The age was right and I ain’t tellin’ LOL

    Why on earth this evening while I have toothache? Aaagh – I can’t look at my favourite foodstuff.

  3. Haha Good one Cherie and it’s quite correct!

  4. ubermouth says:

    I was too tired to do the maths but now I am craving chocolate.

    Sorry, I phased out and started drooling at picture 3, what was the question?

  6. Phidelm says:

    Amazing, Cherie – but how on earth do the calculations work? Will be sure to get latest lot of iron rations @ chocolatier tomorrow … ;-) !

  7. Yum, yum, I’ve come over all religious all of a sudden…

    That was fun! I love the chocolate calculator.

  9. liz says:

    Yes! Very ingenious. I’m sure these things are very logical really but it certainly seems like magic!

  10. Sean Jeating says:

    Well, you need three variables.
    x for how often you think of choc,
    y for the year of your birth
    z for either 1759 or 1758

    And here we go:
    (2x + 5) 50 + z – y

    It works as long you are not 100 years and older. In this case you’d have to vary a bit.

    Ah, math is so sweet. :)

    And so is this post which I enjoyed very much.

  11. Sean Jeating says:

    Well, next year z has to stand for 1760 respectively 1759, so that you will get either 2010 (had already birthday)or 2009 (had no birthday yet):
    Example (leaving the subtraction of one’s year of birth aside):
    (2x + 5) 50 + z
    100 x + 250 + 1760 / 1759 = 2010 /2009

    and so forth: in 2015 z becomes 2015 / 2014, in 2525 it becomes 2525 / 2524. :)

  12. Sean Jeating says:

    Peeeh! :) Sorry.
    Of course, in 2015 to get 2015 respectively 2014 z has to become 1765 / 1764.

  13. Sean,
    I am thankful for math persons. :)
    You made it out so simply…to see the algebra makes sense; to come up with it initially, is another story…

  14. Hi CherryPie,
    my comment the other day must not have posted…so, ‘thanks, this was fun!’ :)

    • CherryPie says:

      The comments do occasionally go a little quirky. I occasionally get threads where the comments won’t let me comment on my own blog!

      Glad you enjoyed it and I am glad Sean explained how it worked :-)

  15. Claudia says:

    Thanks, CherryPie – I enjoyed the chocolate illustrations immensely. I actually had to buy some sweets after I viewed your post. But I didn’t do the calculation. I’m terrible at math. Even Sean’s brilliant exposé would not convince me to try. The point is I’m not interested at all in finding out how old I am. The less I know on that subject, the better I feel.

    • CherryPie says:

      There are some good ones in there (non of them mine). I don’t know how I managed to post it, I am supposed to be on a diet ;-)

      Maths isn’t my favourite subject either.
