(b) {-36,-25,-16, -9,-4,-1}.
3. A proper subset of a set S is a subset of S which is not equal to S itself. Some people
write "A <B" to mean "A is a proper subset of B", but other people use this notation in
the same way as "A ≤B"; to be unambiguous, it is better to write "AB" to mean “A
is a proper subset of B".
Write down all true statements of the form
by Ø, Z, {0, 1), and [0, 1].
4. Find all subsets of S = {0, 1, {0, 1}} which are not also elements of S.
(Another way of writing this problem could be "List all the elements of P(S)-S".)
5. Using the sets A = {1,2,3}, B = {3,4,5}, and C = {2,4,6} and the operations U (union),
n (intersection) and - (set difference), write down an expression that gives the set
{2,3,4,5).
6. A subset of the number line is drawn below and continues by the same pattern indefi-
nitely to the right.
