Hi,I think you can try this way. Consider U (Union) as OR gate and Intersection as AND gate. Then you can come at the solution

RE: A 0 0 0 0 1 1 1 1B 0 0 1 1 0 0 1 1

A: 1 1 0 1 1 0 1 1

B: 0 1 1 1 1 0 1 0

by binary sub. a-b = 01100001 (1-0=1, 1-1=0,0-0=0, now (a-b)uc= 01100001

or 01101101

gives 1101101... convert to decimal equals 109

RE: A 0 0 0 0 1 1 1 1B 0 0 1 1 0 0 1 1C 0 1 0 1 0 1 0 1Find ( A u B ) n C

To find A-C, We will find 2's compliment of C and them add it with A,
That will give us (A-C)
2's compliment of C=1's compliment of C+1
=10101010+1=10101011
A-C=10101011+00001111
=10111010
Now (A-C) U B is .OR. logic operation on (A-C) and B
10111010.OR . 00110011
The answer is = 10111011,
Whose decimal equivalent is 187.
