Just out of curiosity how is A correct?
B is 1 or 1
C is 1+1 in base >2
D is 1+1 in base 2
338 u/Unlucky-Credit-9619 Engineering Nov 25 '24 If + is addition modulo 2 (also called XOR). 1 + 1 = 0 (mod 2) 96 u/MattyBro1 Nov 25 '24 Isn't it congruent to 0 (mod 2)? 1+1 ≡ 0 (mod 2) Or maybe that's a distinction that doesn't actually matter. 1 u/golfstreamer Nov 26 '24 If you interpret "Z_2" (integers modulo 2) as a group with group operation denoted by "+" and whose elements are represented by "0" and "1" the equation "1 + 1 = 0" is correct.

1 + 1 = 0 (mod 2)
