Usage notes[edit]
 In mathematical expressions, the relative complement of A in B is denoted B ∖ A according to the ISO 3111 standard (sometimes written B − A, but this notation is ambiguous, as in some contexts it can be interpreted as the set of all b − a, where b is taken from B and a from A).
Translations[edit]
