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
| |
| 876 | Enter + 876 , Pull handle
| 999999457 | Enter - 543 < 543 - 1 in "9-Complements" >,

===================================================================
This little machine was a hit in its time, since it weighted only

It was also made and distributed under the name MONARCH ...
