Rules of inference

property of binary operations, for which changing the order of the operands does not change the result

property of binary operations allowing sequences of operations to be regrouped without changing their value

property involving two mathematical operations

pair of transformation rules that are both valid rules of inference

if X implies Y, and X is true, then Y is true

if X implies Y, and Y isn't true, then neither is X

systematic logical process capable of deriving a conclusion from hypotheses

in logic, rule of inference

term

inference rule in logics : with "A or B" and "not A" deduce "B"

non-monotonic inference rule implying that the impossibility to derive a statement allows to infer its negation

theorem

if X and Y can't both be true, and X is true, then Y isn't true
