How to Calculate Your Age by Chocolate

Two Methods:  Chocolate Age Calculation Help  Calculating Your Age by Chocolate 

Yes, it's true: if you are old enough to do mathematics and you like chocolate, you might be able to figure out your age. By crunching these numbers (and a chocolate bar, if you’d like), your age is mathematically revealed. Try it out to see for yourself, and then read on to find out how it works.

>> Calculating Your Age by Chocolate

1. Determine how many times a week you eat or want to eat chocolate. It must be a number between 1 and 10, including 1 or 10.

Let's say you eat chocolate 8 times a week (we won't tell).


2. Multiply that number by 2. 8 x 2 = 16

3. Add 5 to the previous result. 16 + 5 = 21


4. Multiply that by 50. 21 x 50 = 1050


5. Add the current year (Gregorian). 1050 + 2011 = 3061


6. Subtract 250 if you've had a birthday this year. If you haven't had a birthday this year, subtract 251. (Let's say your birthday hasn't passed yet.) 3061 - 251 = 2810

7. Subtract your birth year. (Assuming you were born in 1975...) 2810 - 1975 = 835


8. You'll end up with a 3 or 4 digit number. The last two digits are your age (if you're under 10 years old there will be a zero before your age). The remaining one or two digits will be the number of times per week you eat or want chocolate (the number you specified in the first step). 8 pieces of chocolate a week, 35 years of  age.

How it works

This really does work for anybody 1 to 99 years old, although the chocolate part is just for fun. Here is how the mathematics works:

• Select a number between 1 and 10. Multiply by 2, add 5, multiply by 50. These steps are just a fancy way to push your (or your assistant's) random number out into the hundreds place. Here is what you'll get for all possible selections:

1	350
2	450
3	550
4	650
5	750
6	850
7	950
8	1050
9	1150
10	1250

• Add the current Gregorian year (2012):

1	2361
2	2461
3	2561
4	2661
5	2761
6	2861
7	2961
8	3061
9	3161
10	3261

• Subtract 250 (or 251 if your birthday hasn't happened yet this year). This yields the year of your last birthday (2011 or 2012) plus 100 times your chosen number:

1	2110
2	2210
3	2310
4	2410
5	2510
6	2610
7	2710
8	2810
9	2910
10	3010

• Subtract the year of your birth and get your age plus 100 times your chosen number. Put another way: [Year of your last birthday + (100 x your chosen number)] - Year of your birth = Your age + (100 x your chosen number)

Tips

• This is a nifty trick for kids learning basic mathematics, who can practice it on adults and elicit reactions of surprise and amusement.
• Check your calculations for any mistakes.

Warnings

• Add the requirement to reveal whether a person's birthday has passed or not, and most knowing individuals will come to the conclusion that you are just using the chocolate to smokescreen the actual calculations taking place.
• Your friends may guess how it works, as it requires inputting information from their date of birth into the equation, from which you can calculate a person's age immediately. When doing it with your friends, confirm their age and put in their birth year without telling them.
• This will not work consistently for people who are 100 years old or older.
• This method may not always work.
