If $A = \{2, 3, 5\}$ and $B = \{2, 5, 6\}$,then $(A - B) \times (A \cap B)$ is:

If $A, B$ and $C$ are any three sets,then $A \times (B \cup C)$ is equal to

If $A$ and $B$ have $n$ elements in common,then the number of elements common to $A \times B$ and $B \times A$ is

State whether the following statement is true or false. If the statement is false,rewrite it correctly.
If $A = \{1, 2\}$ and $B = \{3, 4\}$,then $A \times \{B \cap \varnothing\} = \varnothing$.

The Cartesian product $A \times A$ has $9$ elements,among which are found $(-1, 0)$ and $(0, 1)$. Find the set $A$ and the remaining elements of $A \times A$.

If $G = \{7, 8\}$ and $H = \{5, 4, 2\}$,find $G \times H$ and $H \times G$.
