Your age by chocolate :)

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 8 times a week (we won't tell).




Multiply that number by 2.
8 x 2 = 16




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




Multiply 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 1756.
Let's say your birthday hasn't passed yet.
1050 + 1756 = 2806




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 digits are your age!
