Yes, elements in set U are NOT factored into your answer for: A ∩ (B ∪ C)
\n" );
document.write( "A ∩ (B ∪ C)
\n" );
document.write( "∪ INDICATES UNION, which is: ALL ELEMENTS in BOTH sets, EXCLUDING DUPLICATES
\n" );
document.write( "             A ∩ [B + C  -  (B ∩ C)]
\n" );
document.write( "             A ∩ (ALL in BOTH sets, or ALL in B & C, EXCLUDING DUPLICATES)
\n" );
document.write( "        A      ∩ (ALL in B + ALL in C, less ELEMENTS in BOTH B & C)
\n" );
document.write( "  (1, 2, 4, 6) ∩ [(3, 7) + (1, 3, 6, 7, 9)  -  (3, 7)]
\n" );
document.write( "  (1, 2, 4, 6) ∩ (1, 3, 6, 7, 9)
\n" );
document.write( "  A ∩ (B ∪ C) =  \n" );
