System A operators with 8-bit signed numbers. Negative numbers are presented in the 2's complement form. Subtract the binary numbers below by addition of the 2's complement of the subtrahend. Determine both sign and decimal magnitude of the result 11111000-01011100 = System B operators with unsigned BCD numbers presented with 8 bits. Perform bit-by-bit addition of two decimal numbers shown in BCD, show carry bits. Find the decimal magnitude of the result Systems C and D operate with 12-bit codes representing 3-digit signed decimal integers In the 2421 and Excess-3 codes, respectively. Negative numbers are presented in the 10's complement form. -Specify the range of numbers presented in the systems: form to -Show the 2421 code for decimal number "+36" In system C -Obtain the 2421code for the 9's complement of it -Obtain the 2421 code for presentation of "-36" -Show the Ex-3 code for decimal number "+36" in system D -Obtain the Ex-3 code for the 9's complement of it -Obtain the Ex-3 code for presentation of "-36"
