Here is one , that will always result in the number nine, no matter what number is chosen. Follow the steps 1 at a time. # Choose any number. # Add three. # Subtract your number. # Multiply by six. # Divide by two. It is a simple principle, and this is just one example of these 'magical' mathematical 'rules'. Really, it just eliminates your number from the equation without the person following these instructions knowing it, and then having new numbers that eventually equal 9.
