  1. There is a magic number in this trick - it is 130
  2. Ask a friend to make a square around any four numbers on the magic table. We have given you one example in the coloured box.
  3. Look diagonally at the number in the second square from the marked square. In the example it is 30. (You can look diagonally from any corner of the marked square.)
  4. Subtract the number from the magic number 130.(130-30=100)
  5. Now tell your friend the total of the four numbers in the box is 100. He'll be amazed to find you are right.
  6. Try this out with any four numbers in the table. It always works.
