Contrapositive of and statement
WebApr 17, 2024 · The contrapositive is a conditional statement in the form X → (Y ∨ Z. The difficulty is that there is not much we can do with the hypothesis ab = 0 since we know nothing else about the real numbers a and b. However, if we knew that a was not equal to zero, then we could multiply both sides of the equation ab = 0 by 1 a. WebA proof by contradiction proves a statement true that can be proven false (typically is already known to be false) by other means, meaning that the logic being used is inconsistent. Rather than working with a statement directly, it assumes its negation and derives an absurdity. The goal here is to reach a falsehood, not truth.
