If the answer corresponds to a negative value, the answer, in decimal value, will be higher
than 1000.
In that case, it is necessary to convert the value in the following way:
First step: convert the value Hexadecimal into
binary
Hexadecimal :
FFFFFC54
Binary :
1111 1111 1111 1111 1111 1100 0101 0100
Second step: reverse the binary
value :
Binary :
1111 1111 1111 1111 1111 1100 0101 0100
opposite :
0000 0000 0000 0000 0000 0011 1010 1011
Third step: Add + 1
opposite :
0000 0000 0000 0000 0000 0011 1010 1011
+1
