The magician shows five different colored dice; on each of their faces a three digit number is printed. A spectator throws the dice a few times on the table to be sure different numbers come out. After the final throw, he is asked to take his mobile phone and to sum all the five three digit numbers that have come out. The magician will total all five three digit numbers in his head! Once the spectator has the total, the magician, to the audience's amazement, already knows, and reveals the correct number!
