1. State what decimal values the following binary numbers represent if you interpret these binary numbers as either unsigned binary, signed magnitude, ones complement, twos complement, or excess-128 forms:

(a) 0101 1011 (c) 1000 0000 (e) 0000 0000 (g) 0000 0001 (b) 1101 1001 (d) 1111 1111 (f) 1000 0001 (h) 0111 1111

2. Perform each of the following arithmetic operations by first converting the given decimal numbers into 8-bit twos complement form. In each case, comment explicitly on whether youve detected overflow or not at the binary arithmetic level. (Show Calculations)

(a) 50 + 57 (b) 116 - 73 (c) -59 - 46 (d) -73 - 86 (e) 116 + 85 (f) 99 + 63
