Six Card Multiplication
Before the arrival of the participant, place cards 1 (Ace), 2, 4, 5, 7, 8 on the table.
You will also need a calculator.
Ask the participant to choose any card.
In the video we chose # 4.
Follow these instructions:
Multiply the number by 9.
Multiply the answer by 111.
Multiply the answer by 1001.
Divide the answer by 7.
Will each card match a different digit of your answer?
Shuffle the cards. Turn them over one at a time. Find out.
PS: Notice the card sorting dyslexia..:-)
