One's complement representations of integers are used to simplify computer arithmetic. To represent positive and negative integers with absolute value less than 2^{n-1}, a total of n bits is used. The leftmost bit is used to represent the sign: this bit is 0 for positive integers and 1 for negative integers. For positive integers, the remaining bits are identical to the binary representation of the integer. Thus using 4 bits, the One's complement representation of 5 is 0101. For negative integers, the remaining bits are found by first finding the binary representation of the absolute value of the integer and then taking the complement of each of these bits in the binary representation. (Thus 1's and 0's get switched) Thus for example using 4 bits, the One's complement representation of -5 is 1010, where the initial 1 is to indicate the sign, and the subsequent 010 is the complement of 101 the binary representation of 5. Find the One's Complement representations, using bit strings of length six, of the following integers. (Your answers must be bit strings of length 6): (a) 19 (b) 27 (c) -20 (d) -24

In the binary system, each number and its sign are represented using only the digits 0 and 1. Since negative and positive signs cannot be directly written in the binary system, the 2's complement method is used as an alternative to represent negative and positive numbers. This method has an interesting property that allows for easy binary arithmetic operations on signed or unsigned numbers. Compute the following binary arithmetic operations using the 2's complement method. (Show all steps clearly.) a) Sum of -9 and 17 b) Sum of -20 and -14 c) Multiplication of -4 by 13 d) Multiplication of -8 by -12
