implication

Từ điển Máy Tính - Foldoc Dictionary

implies

(logic)   (=> or a thin right arrow) A binary Boolean function and logical connective. A => B is a true implication unless A is true and B is false. The truth table is

 A B | A => B  ----+-------  F F |   T  F T |   T  T F |   F  T T |   T 

It is surprising at first that A => B is always true if A is false, but if X => Y then we would expect that (X & Z) => Y for any Z.

If A is actually an expression X & Y then the implication is called a syllogism.
