5) Consider the ollowing sets, S, together with the defined binary operation. In each case, determine if the set is closed under the given operation, if the operation is associative and if the operation is commutative: ii) S R a -a b 6) Define the binary operation, multiplication modulo 3 in much the same way as we did addition modulo 3. That is, perform ordinary multiplication and then reduce the result modulo 3. Let S-(0, 1,2. Create two...

Question 2 please
Exercise 1. Define an operation on Z by a b= a - b. Determine ife is associative or commutative. Find a right identity. Is there a left identity? What about inverses? Exercise 2. Write a multiplication table for the set A = {a,b,c,d,e} such that e is an identity element, the product is defined for all elements and each element has an inverse, but the product is NOT associative. Show by example that it is not associative....

5) Determine whether the given definition does give a binary operation on the indicated set. In other words determine whether the given ser is closed under the given operation. • If so, prove that it satisfies closure. . If not, find a counter-example and show how it fails closure. e. On K = { : a, b e m}, under usual matrix multiplication X.

1. Express in the language of the FOL the following mathematical statement: If S is a set of elements and * is a binary operation in S for which the following four assumptions hold, where = is an equivalence relation: a. S is closed under * ( if x and y are in S then x * y is also in S) b. * is associative (x, y, and z in S (x * y) * z = x *...

Let S = {x ER:[x]<1}=(-1,1). We will refer to E as hyperbolic relativity space. Now a+b define a binary operation by: if a,beR and ab +-1, then aob= 1+ ab Proposition 1. (5,0) is a group. Remark. This is the kind of problem that every student should become competent at doing. Perhaps some of the details here are more challenging than normally but understanding what are the steps to follow in such a problem is basic, and everyone should understand...
