SUBTRACTION:
============
Addition is the only operation directly performed on the machine.
For subtraction an indirect method of addition is necessary!

The "9-Complement" Methode:

           KEY-Figures  =   1   2   3   4   5   6   7   8   9
       "9-Complements"  =   8   7   6   5   4   3   2   1   0

Entering the SUBTRAHEND requires 2 steps:
----------------------------------------------------
(A) SET ALL 9s LEFT OF THE SUBTRAHEND 
(B) Enter the SUBTRAHEND MINUS 1 use the "9-Complements"

PRINTOUT-Example    876 - 543  =  333    with Comments:
*******************************************************

^^^^^^^^^^^^^^^^^   To clear memory:
|            *  |   Press [T=Total], Pull handle

|               |                  Pull handle
|        333 *  |   Press [T] to print total sum, Pull handle
