Prove that the set R = {0,1,2,3,4,5} is a commutative ring with
respect to the operations of addition modulo 6 and multiplication
modulo 6.
Let p = (8, 10, 3, 11, 4, 0, 5, 1, 6, 2, 7, 9) and...
Let p = (8, 10, 3, 11, 4, 0, 5, 1, 6, 2, 7, 9) and let q = (2,
4, 9, 5, 10, 6, 11, 7, 0, 8, 1, 3) be tone rows. Verify that p =
Tk(R(I(q))) for some k, and find this value of k.

Let B be the set of
all binary strings of length 2; i.e. B={ (0,0), (0,1), (1,0),
(1,1)}. Define the addition and multiplication as coordinate-wise
addition and multiplication modulo 2. It turns out that B becomes a
Boolean algebra under those two operations. Show that B under
addition is a group but B under multiplication is not a group.
Coordinate-wise
addition and multiplication modulo 2 means (a,b)+(c,d)=(a+c, b+d),
(a,b)(c,d)=(ac, bd), in addition to the fact that 1+1=0.
Let A = {0, 3, 6, 9, 12}, B = {−2, 0, 2, 4, 6, 8,...
Let A = {0, 3, 6, 9, 12}, B = {−2, 0, 2, 4, 6, 8, 10, 12}, and C
= {4, 5, 6, 7, 8, 9, 10}.
Determine the following sets:
i. (A ∩ B) − C
ii. (A − B) ⋃ (B − C)
