Explanation
XOR is similar to the OR gate, but the numbers can not be equal. (ex. 0V0=0; 1V0=1; 0V1=1; 1V1=0)
Above 1 and Below 0
I tried to research and work on numbers above 1, but it gets kind of confusing, at first it is simple(ex. (1,2)=3; (2,2)=0; (4,2)=6; (5,2)=7;), but then when you input (6,2) it equals 4. I tried working on this for half and hour with no luck. When I tried to work on numbers below 0 at first it was as confusing as above 1 and as simple as 0 and 1, but still a positive number. Then when I mixed negative and positive, I got 4294967295 from (-1,1). I didn't try to research it. So hopefully someone will edit this and explain how going above 1 works, and possibly include an equation or 2.
