To add (+5) and (-5) in Signed Magnitude (SM), you need to follow these steps:
Step 1: Convert the numbers to their signed magnitude representation.
(+5)SM = 0101
(-5)SM = 1101
Step 2: Determine the sign of the result.
Since one number is positive (+) and the other is negative (-), the result will be negative (-).
Step 3: Perform the binary addition while discarding any overflow.
0101 (+5)
+1101 (-5)
____
10010
Step 4: Convert the result back to its Signed Magnitude representation.
The result, 10010, in Signed Magnitude is (-2)SM.
Therefore, the correct answer is (-2)SM.
