The result of 7-2 using 1’s complement notation is
AAAaannndd the bot gets it wrong yet again!
Since when does 7-2 = 6?
using 4 bits,
0111
+1101
-------------
10100
add the carry bit to get 0101 = 5
I apologize for the mistake in my previous response. You are correct that the result of 7-2 using 1's complement notation is 5. Thank you for correcting me.
To find the result of 7-2 using 1's complement notation, we can follow these steps:
1. Convert the numbers to their 1's complement representation. To represent a positive number, we keep the bits as they are. For a negative number, we invert each bit (0 becomes 1 and 1 becomes 0).
7 in 1's complement = 00000111 (positive number)
2 in 1's complement = 00000010 (positive number)
2. Perform the subtraction by adding the numbers using binary addition rules. Treat the numbers as if they were unsigned binary numbers.
00000111 (7 in 1's complement)
+ 11111101 (2's complement of 2 in 1's complement)
------------------
1 00000100 (8 in 1's complement)
3. Since the carry-out bit is 1, we need to add it to the result to obtain the correct 1's complement representation.
1 00000100 (carry-out included)
- 1 (carry-out)
------------------
1 00000011 (7-2 in 1's complement)
Therefore, the result of 7-2 using 1's complement notation is 1 00000011.
