two's complement
complément m à deux

Two's complement. A method of storing negative numbers in binary notation so that they can be added and subtracted.

It also shows how to express negative numbers. In a row of binary numbers, the most significant digit (rightmost column) indicates a positive or negative number, regardless of the length of the word.

A 1 in that column indicates a negative number. A 0 indicates a positive number.
Two's complement can also be used to find the negative form of a positive number or vice versa. For example, the usual way to do subtraction is: 7-5=2.

The addition method for subtraction involves adding a number that is the answer, such as:
What number goes to 5 to make 7?
5+? = 7

To find the negative form (or the reverse): What one does is answer the question: What number, when added to the original number, makes it zero? (In other words: the number indicates the reverse form.) For example:

+5-5=0
23 + 23 = 0-

The reverse method: Find the one's complement (reverse all the numbers and add one 1. The two's complement is sometimes called the negation of 1 + negation.
