False obversion is a logical fallacy that occurs when an argument is incorrectly transformed from its original form to its obverse, leading to a misleading or invalid conclusion. In standard obversion, the quality of the proposition is changed (affirmative to negative or vice versa), and the predicate is replaced with its complement. However, false obversion fails because it misapplies this transformation, often ignoring essential qualifiers or context, resulting in an argument that does not accurately reflect the original statement. This fallacy can lead to confusion and misinterpretation in logical reasoning.
false
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False

It is false.

inversion is effected by a series of obversion and conversion

Obversion in logic is a type of immediate inference that transforms a proposition into its equivalent by changing its quality and replacing the predicate with its complement. For example, the statement "All cats are mammals" can be obverted to "No cats are non-mammals." Another example is the statement "Some birds are not sparrows," which can be obverted to "Some birds are non-sparrows." In both cases, the truth value of the original statement is preserved.
False
True AND False OR True evaluates to True. IT seems like it does not matter which is evaluated first as: (True AND False) OR True = False OR True = True True AND (False OR True) = True AND True = True But, it does matter as with False AND False OR True: (False AND False) OR True = False OR True = True False AND (False OR True) = False AND True = False and True OR False AND False: (True OR False) AND False = True AND False = False True OR (False AND False) = True OR False = True Evaluated left to right gives a different answer if the operators are reversed (as can be seen above), so AND and OR need an order of evaluation. AND can be replaced by multiply, OR by add, and BODMAS says multiply is evaluated before add; thus AND should be evaluated before OR - the C programming language follows this convention. This makes the original question: True AND False OR True = (True AND False) OR True = False OR True = True
