You can put this solution on YOUR website!
A × B =  {1.2} × {3,4} = {(1,3),(1,4),(2,3),(2,4)}

Subsets are

 1.  ⌀ or { }
 2.  {(1,3)}
 3.  {(1,4)}
 4.  {(2,3)}
 5.  {(2,4)}
 6.  {(1,3),(1,4)}
 7.  {(1,3),(2,3)}
 8.  {(1,3),(2,4)}
 9.  {(1,4),(2,3)}
10.  {(1,4),(2,4)}
11.  {(2,3),(2,4)}
12.  {(1,3),(1,4),(2,3}}
13.  {(1,3),(1,4),(2,4}}
14.  {(1,4),(2,3),(2,4}}
15.  {(1,3),(1,4),(2,3}}
16.  {(1,3),(1,4),(2,3},(2,4)}
