# Chocolate Calculator.

Don't tell me your age; you probably would tell a falsehood anyway

-but the Cadbury Man will know! YOUR AGE BY CHOCOLATE MATH

This is pretty neat.

DON'T CHEAT BY SCROLLING DOWN FIRST!

It takes less than a minute .

Work this out as you read .

Be sure you don't read the bottom until you've worked it out!

This is not one of those waste of time things, it's fun.

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 (just to be bold)

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 ..

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

YOUR AGE! (Oh YES, it is!!!!!)

THIS IS THE ONLY YEAR (2009) IT WILL EVER WORK, SO SPREAD IT AROUND WHILE IT LASTS.

Spooky? Come on people, it's just simple maths!

ie Pick a number between 2 and 9. Let's call the number "n".

So now we have 2n

2n+5 now - getting exciting!

so now up to 100n+250

So this brings us up to 100n+2009 (or 100n -2008 if you've not already had birthday)

Well, if you've already had a birthday, 2009-year of birth = your age

If not then 2008 - year of birth = your age

So now we have in total 100n + (2009 or 2008) - year of birth

which is the same as 100n + your age

But the number n is between 2 and 9, so if you are under 100 that will leave you with a 3 digit number, the first digit of which is the number you started with and the other 2 digits are your age.

Wow!

But if you increase the numbers in step 5 by an extra 1 every year you will find that it just carries on working!
