Set theory MOD Help.

If E = { n e Z:1 =< n =< 12}

A={n e Z:12 mod n=0}
B={n e E: n is a prime number}
C={n e Z: n mod 1=2}

Enumerate the elements of

A U B

______
(A U C)

C - A

Could someone explain in steps how to solve this question?

[color=#000000]The first thing you have to do is to specify the elements of each set. I made some changes because I think that there are problems in the wording of the exercise.

To typeset an arithmetic congruence using the latex tag, please use \pmod as illustrated below:

  (based on x\equiv y\,\pmod n).
