Add the following numbers in binary using 2's complement to represent negative numbers. Use a word length of 6 bits (including sign) and indicate if an overflow occurs (a) 21 +11 1.7 Repeat (a). (c). (d), and (e) using I's complement to represent negative numbers 1.19 Divide in binary (a) 11101001+101 (b) 110000001+1 110 (c) 1110010 1001 Check your answers by multiplying out in binary and adding the remainder Because A-B=A+(-1), the subtraction of signed numberscan be accomplished by adding the complement. Subtract each of the following pairs of 5-bit binary num- bers by adding the complement of the subtrahend to the minuend. Indicate when an overflow occurs. Assume that negative numbers are represented in 1's complement Then repeat using 2's complement (a) 01001 (b) 11010 (c) 10110 (d) 110 (e 11100 1.37 -11010 -11001 -01101 00111 -10101
