I only need question 3, 4, 5 and 6

1. Add the following 8-bit unsigned binary numbers as shown: (3 points) a) 01110101 +00111011 b) 00010101 +0 0110000 c) 11101111 + 01010001 2. Perform the following binary multiplications, assuming 8-bit unsigned integers: (3 point a) 1100 X101 b) 10101 X 111 c) 11010 X 1100 3. Add the following 8-bit signed magnitude binary numbers: (3 points) a) 01100100 +00010100 b) 01001110 +00 101 101 c) 01001110 +01001111 4. Add the following 8-bit one's complement binary numbers: (3 points) a) 01000001 +00110000 b) 10111110 +1 1001111 c) 01111010 +1 1011001 5. Add the following 8-bit two's complement binary numbers: (3 points) a) 01000001 +00101110 b) 01110110 +11010011 c) 11011010 +1 1010011 6. Assuming 8-bit two's complement numbers, subtract the following using two's complement arithmetic: (3 points) a) 110 00100 - 00111011 b) 01011011 -0001 1 1 1 1 c) 10101100 - 00100100
