Given these sets:
\n" ); document.write( "A = {1, 2, 3, 4}
\n" ); document.write( "B = {3, 4, 5, 6, 7}
\n" ); document.write( "C = {3, 5, 7, 9}\r
\n" ); document.write( "\n" ); document.write( "List the elements of this set
\n" ); document.write( "B ∩ (A U C)
\n" ); document.write( "Do not skip to the answer. Show your work, step by step
\n" ); document.write( "
\r\n" );
document.write( "---------------------------------------\r\n" );
document.write( "\r\n" );
document.write( "B ∩ (A U C)\r\n" );
document.write( "\r\n" );

document.write( "We do the parentheses first:\r\n" );
document.write( "\r\n" );
document.write( "{1, 2, 3, 4} U {3, 5, 7, 9} means to list every element\r\n" );

document.write( "\r\n" );
document.write( "So replace the parenthetical part, so we have: \r\n" );
