# exclusive or

The logical operator xor, short for “exclusive or”, is a binary operator that is true iff exactly one of its parameters is true, and thus corresponds to the normal use of “or” in English. Xor uses the symbol $\oplus$ due to its similarity to disjunction, which sometimes uses $+$. The truth table for xor is

$a$ $b$ $a\oplus b$
