TABLES MAGIC

 

 

Don’t know your tables?  Never mind, in this system you don’t need them beyond 5 × 5!

  • Suppose you need 8 x 7

    8 is 2 below 10 and 7 is 3 below 10.
    Think of it like this:



    The answer is 56.
    The diagram below shows how you get it.



    You subtract crosswise 8-3 or 7 - 2 to get 5,
    the first figure of the answer.
    And you multiply vertically: 2 x 3 to get 6,
    the last figure of the answer.

    That's all you do:

    See how far the numbers are below 10, subtract one
    number's deficiency from the other number, and
    multiply the deficiencies together.

  • 7 x 6 = 42



    Here there is a carry: the 1 in the 12 goes over to
    make 3 into 4.
