What, then, does positive 83 look like in nines' complement?

In the first method the nines' complement of x is added to y.

This alternate row contained the nines' complement of the digits.

The nines' complement plus one is known as the tens' complement.

Then the nines' complement of the minuend was entered.

Then the nines' complement of the result obtained is formed to produce the desired result.

The proper use of nines' complement requires no ambiguity in the sign of a written number.

Because of the leading digit of 9, this answer is clearly negative, so its nines' complement needs to be calculated.

Replacing 00391 with its nines' complement produces the sum:

Nines' complement, again in analogy with ones' complement for binary, has two representations of zero.

The nines' complement math breakthrough eliminated the significant mechanical complexity created when "borrowing" during subtraction.

The nines' complement of a number is formed by replacing each digit with nine minus that digit.

The Comptometer had nines' complement digits printed in smaller type along with the normal digits on each key.

Subtraction is done by adding the ten's complement of the subtrahend, which is the nines' complement plus 1.

To form the nines' complement of a larger number, each digit is replaced by its nines' complement.

Pascal's calculator had two sets of result digits, a black set displaying the normal result and a red set displaying the nines' complement of this.

In the decimal numbering system, the radix complement is called the ten's complement and the diminished radix complement the nines' complement.

The slat was then moved to expose the black digits (which now displayed the nines' complement of the minuhend) and the subtrahend was added by dialing it in.

On some machine this could be done by dialing in the minuhend using inner wheels of complements (i.e. without having to mentally determine the nines' complement of the minuhend).

Because nines' complement in decimal is analogous to ones' complement in binary, the leading "1" is an end-around carry and must be moved to the least significant place and added to arrive at the correct result.

In displaying that data in the complement window (red set), the operator could see the nines' complement of the nines' complement of the minuhend, that is the minuhend.
