(1) Arithmetic Addition
In the arithmetic addition, negative numbers are initially in 2'scomplement, and if the sum obtainedafter the addition is negative,it is in 2's-complement form. The addition of negative numbers isobtainedfrom the addition of their corresponding signed binarynumbers represented in signed-2'scomplement form,including theirsign bits. And, a carry out of the sign-bit position isdiscarded.
In the above four examples, each operation performed is additionwith the sign bit included. Anycarry out of the sign-bit positionis discarded, and negative results are automatically in 2'scomplementform. To determine the value of a negative numberwhen.it's in signed-2's complement, it is necessary toconvert it toa positive number to place it in a more familiar form.
The procedure is very simple. For example, the signed binary number11010101 is negativebecause the leftmost bit is ,1, that is, its2's complement is 00101011, which is the binary equivalent Of+43.Therefore, the original negative number is equal to-43.
(2) Arithmetic Subtraction
Take the 2'S complement of the subtrahend (including the sign bit)and add it to the minuend(including the sign bit). A carry out ofthe sign-bit,'position is discarded.
