Distributive laws (分配率): P∨(Q∧R)=(P∨Q)∧(P∨R) P∧(Q∨R)=(P∧Q)∨(P∧R) Absorption laws (吸收律): P∨(P∧Q)=P,P∧(P∨Q)=P Double negation law (双重否定律): ¬¬P=P 变量和集合: P={x|x satisfies some conditions} x是变量, P是满足条件的所有x的集合. A∪...
complement of A: U-A, where U is the universal set set identities: set equations no matter what set is, including distributive laws, De Morgan's law, and so on. They can be prooved by mathematic logic and definations of set computer representation of sets: assume the universal set U i...
What is a preimage in math? What is isotopy in topology? What are centralizers in abstract algebra? State which property is demonstrated: distributive, associative, or neither. 3(bz) = (3b)z Prove that p implies q is logically equivalent to not q is to not p. I.e., prove that an...
