Consider the binary bit pattern 1 0 0 0 1 0 0 1 0 0 1 1 1 0 0. As discussed in class, the same bit pattern can represent different values in different contexts or systems. What is the actual decimal value represented by this pattern in each of the following systems? - The system of unsigned binary numbers - The system of signed binary numbers in Sign-Magnitude (SM) format - The system of signed binary numbers in 1's complement format - The system of signed binary numbers in 2's complement format

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
