  1. 111/(1+1+1)=37
    222/(2+2+2)=37
    333/(3+3+3)=37
    444/(4+4+4)=37
    555/(5+5+5)=37
    666/(6+6+6)=37
    777/(7+7+7)=37

  2. The Magic Number 1089:
    • Use your first piece of paper to write down the number "1089". After you write down the number, ball it up and place it on the floor.

    • Use your first piece of paper to write down the number "1089". After you write down the number, ball it up and place it on the floor.

    • Tell your friend to reverse the digits.For example, 742 is reversed to 247. Next, tell your friend to subtract the bigger number and the smaller number.

    • Tell your friend to reverse the answer he just got. After that, your friend should add up the last two digits.

    • Your friend should come up with a total of 1089. Ask your friend the answer he/she got. When he/she tells you the answer, grab the piece of paper that you had on the floor. Unball the piece of paper and show your friend.

    • Your friend will be amazed!



    Examples: A. 753 - 357 = 396 B. 396 + 693 = 1089 A. 846 - 648 = 198 B. 198 + 891 = 1089 As you can see, the answer will always be 1089

  3. If you multiply the number 142,857 by anything between 1 and 6

    the answer contains the same digits.

    e.g. 142857 x 3 = 428571 and 142857 x 6 = 857142

    If you multiply the same figure by 7 the answer is 999,999.
