We introduced the notion of anti-vague deductive systems in subtraction algebra in this paper and study some findings on anti-vague deductive subtraction algebra systems and we for all intents and purposes come out with sort of possible theorems and evidence in a sort of major way. The relation between the anti-vague deductive system and the really crisp deductive system for all intents and purposes is also discussed, demonstrating how the relation between the anti-vague deductive system and the particularly crisp deductive system actually is also discussed
