The Multiplication<\/h3><\/span>
<\/div><\/div><\/div>\n

This machine is a half-automatic machine. It means that, for the multiplication, figures are entered, one by one, on the multiplier keyboard, and partial results are displayed on the cumulative Register, by adding the product of this computation (multiplicand multiplied by one digit of the multiplier).<\/p>\n

The steps are descibed here, for the multiplication 4869 x 176<\/strong>:<\/p>\n

    \n
  1. Set the multiplicand on the keyboard, by typing 4,8,6,9 at the right<\/li>\n
  2. Make sure that the lever, at left, is on “Add\/Mult” and press the “REP” key<\/li>\n
  3. As the multiplier has 3 digits, the carriage has to be moved 3 positions to the right, before initiating the computation<\/li>\n
  4. Press key “1” on the multiplier keyboard. The carriage is automatically shifted one position to the left and the partial result is displayed<\/li>\n
  5. Press key “7” on the multiplier keyboard. Again, the carriage is shifted to the left and the partial result is added to the cumulative Register<\/li>\n
  6. Finally, press “6” on the multiplier keyboard. Now the carriage has moved to its home position and the final result is displayed<\/li>\n
  7. The final result is 856’944<\/strong><\/li>\n<\/ol>\n
