Integer Addition
Give the 8 bit binary result for each addition of two 8 bit numbers. Considering both signed (twos complement) and unsigned arithmetic, is the result a legal number? Characterize each as:

1. Correct for both signed and unsigned representations

2. Correct for signed and incorrect for unsigned representations

3. Correct for unsigned and incorrect for signed representations

4. Incorrect for both signed and unsigned representations

11011001 + 01100011 =

01001000 + 00101100 =

01110000 + 01101100 =

10110000 + 10110000 =

11011001 + 11100011 =

Explanation / Answer

11011001 + 01100011 =0100111100
01001000 + 00101100 =01110100
01110000 + 01101100 =011011100
10110000 + 10110000 =0101100000
11011001 + 11100011 =0110111100
