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 (including the weekly frequency of your preference for chocolate), your age is mathematically revealed. It's a nifty trick for kids learning basic mathematics, who can practice it on adults and elicit reactions of surprise and amusement. Try it out to see for yourself, and then read on to find out how it works.
Steps
Determine how many times a week you eat or want chocolate. It must be a number between 1 and 10, including 1 or 10.
Let's say you eat chocolate (http://www.wikihow.com/Eat-Chocolate) 8 times a week (we won't tell).
Multiply that number by 2.
8 x 2 = 16
Add (http://www.wikihow.com/Add) 5 to the previous result.
16 + 5 = 21
Multiply (http://www.wikihow.com/Multiply-Using-the-FOIL-Method) that by 50.
21 x 50 = 1050
Add 1757 if you've had a birthday this year. If you haven't had a birthday this year, add (http://www.wikihow.com/Add-Large-Numbers) 1756.
Let's say your birthday hasn't passed yet.
1050 + 1756 = 2806
Subtract (http://www.wikihow.com/Subtract) your birth year.
Assuming you were born in 1975...
2806 - 1975 = 831
You'll end up with a 3 digit number, the first digit (in the hundreds place) is how many times a week you eat or want chocolate (the number you specified in the first step). The next two numbers are your age!
Why it works
This really does work for anybody from 1 to 99 years old, although the chocolate part is just for fun (and added distraction). Here's how the mathematics work.
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:
2 450 3 550 4 650 5 750 6 850 7 950 8 1050 9 1150
Add 1757 or 1756, if your birthday hasn't happened yet this year. This yields the year of your last birthday (2006 or 2007) plus 100 times your chosen number:
2 2206 3 2306 4 2406 5 2506 6 2606 7 2706 8 2806 9 2906
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)
Warnings
This will only work in 2007! For 2008, in Step 5, add 1758 if your birthday went by and 1757 if it didn't yet.
