Question 1: (4 +16 = 20 points) (a) Perform the following arithmetic operations using non signed numbers representation (1011.01)2 - (11101.11)2 (Show the carry after each addition of two digits) (b) Convert A (12.5)1o and B- (1.40)16 into binary format employing 7 bits for the integer part and 3 for the fractional part, including the sign bit. Perform the following operations in specific signed complement as indicated for each operation. (i) C=-A-B ii) D-A B (iii) E A-B using signed 1's complement using signed 2's complement using 9's complement (show all intermediate steps) Question 1: (4 +16 = 20 points) (a) Perform the following arithmetic operations using non signed numbers representation (1011.01)2 - (11101.11)2 (Show the carry after each addition of two digits) (b) Convert A (12.5)1o and B- (1.40)16 into binary format employing 7 bits for the integer part and 3 for the fractional part, including the sign bit.
