SUM (Ternary Gate)

Modulo-3 Sum

Uses

While there is a ternary XOR gate, it's usefulness does not align with what the binary XOR can do.

Sum does mod 3 addition, returning the remainder. Takes the place as an XOR in an adder.

It is also useful for cryptography being symmetrical, self-negating, associative, and commutative.

A ⊕ B = C
C ⊕ A = B
A ⊕ C = B
B ⊕ C = A
A ⊕ 0 = A
0 ⊕ A = A
