Chocolate maths!

Give this a go - 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!

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!
