12. Use 4-bit binary addition, perform -2 + 2. First convert the decimal numbers to signed 2's complement binary numbers. Circle the lower 4 bits of the answer. Is the 4-bit answer correct? There is a short cut to taking the 2's complement. You can flip every bit to the left of the right most one. Let's try it. (+3)10=(0011),2. If we flip every bit to the left of the rightmost 1 (which is in bold and underlined) we'll get (1101), which according to the table above is (-3)10! Let's try another. (-6)10 = (1010),. If we flip every bit to the left of the rightmost 1 (in bold and underlined) we'll get (0110), which is (+6),0- %3D
