Recurring
Number
.
Write
down the
following 8 digit number
on a piece of paper: 1 2 3 4 5 6 7 9
Ask a participant to circle one of the digits.
Example
: the
participant circles number 7.
Now ask the participant to multiply the 8 digit number by 63.
A magic result happens :
1 2 3 4 5 6 7 9 x 6 3 = 7 7 7 7 7 7 7 7 7
The answer is a row of the chosen number 7.
How
to do this math trick:
When the participant circles a number, you need to multiply the chosen
number by 9.
Example:
if 3
was chosen you would multiply 3 x
9 = 27.
Then you would ask the participant to multiply the 8 digit number by
the number you obtained (27)
Therefore multiply 12345679 by 27 and you magically get the
answer 333333333.
Einstein would be proud!
