You write down the following 8 digit number on a piece of paper

1 2 3 4 5 6 7 9

Then ask your friend to circle one of the digits. Say 5

You then ask your friend to multiply the 8 digit number by 45, and magically the result ends up being:**1 2 3 4 5 6 7 9****x 4 5****---------------****5 5 5 5 5 5 5 5**

with the answer as a raw of the chosen number 5**The Secret!!!**

When your friend circles a number, you need to multiply the chosen number by 9 in your head. Then you need to ask your friend to multiply the 8 digit number by the number you have worked out and you magically get the answer as a raw of the chosen number.
