Below is a proposition about rings, and a short proof in which the use of the axioms and other properties of rings is not made explicit. Proposition. Let R be a ring. For any two elements a and b of R, it holds that -(ab) = (-a) b. Proof. We have -(ab) + ab= 0 and (-a) b + ab= 0. Therefore -(ab) = (-a)b. Which property is used to prove -(ab) + ab=0? This property and two more are used to prove (-a) b + ab=0. What are the other two? Put them in the order you would use them when simplifying (-a) b + ab to 0. First then Which property is used to finish the proof? Please look at the lecture notes to remind yourself e.g. what "Proposition 3.13" is. commutative law for + associative law for • definition of inverse for + identity law for + identity law for. definition of inverse for. > associative law for + Proposition 3.13 cancellation property distributive law
Let S = {4, 7, 41, 74}. Recall that the power set P (S) of S is the set of all subsets of the set S. Notice that (P (S);A,n) is a commutative ring with unity, where AAB = (A – B)U (B – A) for any A, BE P (S) and -, U,n are the usual set difference, union, and intersection, respectively. List the elements of the following sets: a. The additive identity, which is the element with respect to A, is the set b. The the additive inverse of A = {4}, which is the inverse of A with respect to A, is the set c. The unity is the set d. The set S = {4,7, 41, 74} is ? v since the additive identity the unity e. The set A = {4} is ? v since An ? f. The ring (P (S);A,n) is ?
