random number and you're instantly able to create a magic square
of numbers in which all rows, columns, diagonals and corners

below shows the basic framework for the square: The numbers
shown in the above square will always be present, whatever
random number is chosen. You need to memorize the order and
positions of those numbers. The grey squares A to D are where
you will add additional numbers to complete the magic square. If
like me you have a terrible memory, write the basic framework of
the magic square using very light pencil in the corner of your
notepad or flip chart. It will be visible to you but not to your
audience. To begin, ask for a random number between 25 and 100.
Let's say your spectator chooses the number 37. Subtract 21 from
the number given (in this example, we get 16) and put it in
position A. Then add 1
