WebWith two’s complement, an overflow with a large positive value can produce a negative answer. For example, say I am working with 4-bit two’s complement numbers. The largest positive number we can write in two’s complement with four bits is 0111 or 7. Now say I add 5 + 5 (0101 + 0101): WebFor example: In this example, we are going to add 7 and 1 with the help of 2's complement. Solution: The addition of binary number 7 (0001) and 7 (0111) is described as follows: 0001 (1) + 0111 (7) = 1000 (-8) As we can see that adding 7 + 1 with the help of 4 bit is equal to 8. But we cannot represent 8 with the help of 4 bit 2's complement ...
