(3) Let m be a positive integer. (a) Prove that Z/mZ is a
commutative ring. (b) Prove that if m is composite, then Z/mZ is
not a field.
(4) Let m be an odd positive integer. Prove that every integer
is congruent modulo m to exactly one element in the set of even
integers {0, 2, 4, 6, , . . . , 2m− 2}

Suppose A = {(a, b)| a, b ∈ Z} = Z × Z. Let R be the relation
define on A where (a, b)R(c, d) means that 2 a + d = b + 2 c.
a. Prove that R is an equivalence relation.
b. Find the equivalence classes [(−1, 1)] and [(−4, −2)].
4. Show that the set A = {fm,b : R → R | m does not
equal 0 and fm,b(x) = mx + b, m, b ∈ R} forms a group
under composition of functions. (The set A is called the set of
affine functions from R to R.)
I am so lost on this. I am making a B in this class but I can
not seem to get this project completed. Please help.
