\n" ); document.write( "Start with the universal set U
\n" ); document.write( "U = {q, r, s, t, u, v, w, x, y, z}\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cross off anything you find in set A = {q, s, u, w, y}
\n" ); document.write( "U = {q, r, s, t, u, v, w, x, y, z}
\n" ); document.write( "U \ A = {q, r, s, t, u, v, w, x, y, z} blue items are crossed off the list
\n" ); document.write( "U \ A = {r, t, v, x z}
\n" ); document.write( "A ' = {r, t, v, x, z}
\n" ); document.write( "The notation U \ A tells the reader to \"start with set U and kick out the items in set A\", which is what a complement set is. We write A', or A prime, to indicate a complement set to set A.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then union this with the items in set B.
\n" ); document.write( "
\r\n" );
document.write( "A' U B = {r, t, v, x, z} U  {q, s, y, z}\r\n" );
document.write( "A' U B = {r, t, v, x, z,     q, s, y, z}\r\n" );
document.write( "A' U B = {q, r, s, t, v, x, y, z}\r\n" );
document.write( "
Notice I sorted alphabetically and tossed out the duplicates\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The union of two sets is the result of combining the two sets together. Almost like we're dumping the two smaller sets A' and B into one larger bin.
