does (11001010)2 - (1001011)2 = (1111111)2?
does (11001010)2 - (1001011)2 = (1111111)2?
(11001010)2 - (1001011)2 = (1111111)2
for implementing the subtraction, we first take (1001011)2 's 1's complement.
as (11001010)2 has 6bits, therefore we have to add a '0' on the left-hand side of (1001011)2
the complement of (01001011)2 is 10110100
now add the numbers,
1 1 0 0 1 0 1 0
+ 1 0 1 1 0 1 0 0
carry-> 1| 0 1 1 1 1 1 1 0
add the carry 0 1 1 1 1 1 1 0
+1
0 1 1 1 1 1 1 1
or we can write (1 1 1 1 1 1 1)2
