To see the antimonotonicity property, recall that x ≤ y is equivalent to x ∨ y = y. Hence γ ( x ∨ y) = γ ( y) and, by De Morgan's law, γ ( x) ∧ γ ( y) = γ ( y) which in turn is equivalent to γ ( y) ≤ γ ( x ).

They are: WebbIn this last video on sentential logic, though not the last on symbolic logic, we finish up our proofs of the rules of replacement with proofs for both forms... In boolean algebra, we make use of logic gates. These logic gates work on logic operations. Here, A and B become input binary variables. "0's" and "1's" are used to represent digital input and output conditions. Thus, using these conditions we can create truth tables to define operations such as AND (A•B), OR (A + … Visa mer Demorgan's law can be used in boolean algebra as well as in set theory to simplify mathematical expressions.
