E Write to dCode! There may be several minimal representations for the same expression, dCode provides a solution and output an algebraic notation. Q For example, the following predicate is true: 1>2 or 2>1 Now, let us type a simple predicate: 1>2 The calculator tells us that this predicate is false. The normal disjunctive form (DNF) uses a sum of products (SOP): The normal conjunctive form (CNF) or clausal form uses a product of sums (POS): The calculation steps, such as a human imagines them, do not exist for the solver. The first line in the proof does not have a label. four minutes B What are boolean algebra simplifications methods? p = It is false that he is a singer or he is a dancer.
