can anyone do this question?
Hey
Do you know what Z6 means? What exactly is your question?
(1*1) mod 6 = 1
(1*2) mod 6 = 2
....
(1*5) mod 6 = 5
(2*1) mod 6 = (1*2) mod 6 = 2
(2*2) mod 6 = 4
(2*3) mod 6 = 6 mod 6 = 0
(2*4) mod 6 = 8 mod 6 = 2
(2*5) mod 6 = 10 mod 6 = 4
....
and so on.
Does it help?

The values for are on the main diagonal,
