For unsigned number computations, no need to add one more additional bit for computations or calculations. But, while doing signed numbers computations (-ve numbers), Then we need to add one more bit for signed representation. Then the total area, power, the cost will be more, due to increasing of area. To solve this problem, the alternate method is "complements". The complement is used for representing ' the negative decimal number in the binary form '. Different types of complement are possible of the binary number, but 1's and 2's complements are mostly used for binary numbers. Generally, they are r's and (r-1)'s complement is possible, but r---> should be is even number Addition rules: su...
