In the case that we're talking about binary numbers, 10 (read "one zero") is the same as the decimal number 2. And 2+2=4.
20 = 400
x = 2
If I am correct, 9 plus 7 equals 112.
x = -8, y = 10
10 + y = 4y = 4 - 10 y = -6
-4 plus 10 equals 6.
A equals 4 because 4 plus 6 is 10 or 10 minus 6 is 4.
Yes.

6+1 equals 7. Plus 3 equals 10. Plus 4 equals 14.
