OTTOTO Convert the following six-bit was complement numbers to decimal (a) (b) 010111 110111 011111 100000 (c) (d) 1.8 Show each of the following calculations in 4-bit two's complement notation. In cach case, convert the result (in binary) back to a decimal number (a) -5+7 (e) 6-4 Suppose we use six bits to represent a two's complement binary number (a) What is the largest number that can be represented? What is the smallest number that can be represented? (c) How many total base-10 numbers can be represented? 1.10. Suppose we use six bits to represent a two's complement binary number. Perform the following additions, indicating when overflow occurs: (b) 010101 001101 100000 110011 + 100110 111111 (c) 010101 101111 1.11. Suppose we use six bits to represent a two's complement binary number. Perform the following subtractions, indicating when overflow occurs: (b) (a) 010101 001101 100000 110011 (c) 010101 101111 100110 111111
