Question: what's the answer for that question:
A, B and C are 8 bit no's. They are as follows:
A -> 1 1 0 0 0 1 0 1
B -> 0 0 1 1 0 0 1 1
C -> 0 0 1 1 1 0 1 0 ( - =minus, u=union)

A-C is the substraction of two binary numbers
ie A is added to the complement of C
which gives
10001011.
the unoin operation if considered as the 'or' operation ie /
we have 10001011 / 00110011 then we have the answer as
10111011.
please let me know to deduce the correct ans if the above is wrong.
