WebMar 24, 2024 · "Implies" is the connective in propositional calculus which has the meaning "if A is true, then B is also true." In formal terminology, the term conditional is often used to refer to this connective (Mendelson 1997, p. 13). The symbol used to denote "implies" is A=>B, A superset B (Carnap 1958, p. 8; Mendelson 1997, p. 13), or A->B. The Wolfram … WebIf B's elements were written first, the union of A and B could be written as {3, 5, 7, 1, 2}. The order in which elements are listed in a set does not matter; the number of elements and the values of the elements determine the set, so the above 2 sets are equal, as are any sets including all the same elements written in different orders.
