Unformatted text preview: have subtraction circuitry within the silicon in addition to the addition circuitry. The decimal number 7 is represented in 2's complement as follows (with the sign bit shown in RED ): 8bits: 7 in binary = 00000111, complementing each bit = 11111000, and adding 1 to the complemented number gives the 2's complement representation of 7 = 1 1111001 . 16bits: Using the same approach, the 2's complement of 7 = 1 111111111111001 . 32bits: 2's complement of 7 = 1 1111111111111111111111111111001 ....
