Math Concept: Your Age by Chocolate Math

1. Pick the number of times a week that you would like to eat something 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. Go ahead, use a calculator if you want.

5. If you have already had your birthday this year add 1762. If you haven’t, add 1761.

6. Now subtract the four digit year that you were born. You should have a three digit number.

Look at that number. The first digit of this was the number of times you said you wanted to eat chocolate every week.

The next two numbers are YOUR AGE!

That's great, but it's a simple maths concept. But it is a good trick. Even I have a few such trick, I would be loving to see more such tricks.
