\r\n" );
document.write( "Order of operations to be attended to:\r\n" );
document.write( "\r\n" );
document.write( "1. Parentheses\r\n" );
document.write( "2. Exponents\r\n" );
document.write( "3. Multiplications or divisions\r\n" );
document.write( "4. Additions or subtractions:\r\n" );
document.write( "\r\n" );
document.write( "We just do one thing at a time and copy everything else over:\r\n" );
document.write( "\r\n" );
document.write( "42/3*7-2(5*4+3)\r\n" );
document.write( "\r\n" );
document.write( "First we look for the highest order of operations that\r\n" );
document.write( "occurs.  That's parentheses:\r\n" );
document.write( "\r\n" );
document.write( "We find 5*4+3 in parentheses, so that's where we start: \r\n" );
document.write( "\r\n" );
document.write( "Within that parentheses, the highest order of operations that\r\n" );
document.write( "occurs is multiplication, so we perform the 5*4 and replace\r\n" );
document.write( "it with 20, copying everything else over:\r\n" );
document.write( "\r\n" );
document.write( "42/3*7-2(20+3) \r\n" );
document.write( "\r\n" );
document.write( "Again we look for what's between parentheses:\r\n" );
document.write( "\r\n" );
document.write( "We find 20+3 in parentheses, \r\n" );
document.write( "\r\n" );
document.write( "Within that parentheses, the highest (ONLY!) order of operations \r\n" );
document.write( "that occurs is multiplication, so we perform the 20+3 and \r\n" );
document.write( "replace it with 23, and copy everything else over:\r\n" );
document.write( "\r\n" );
document.write( "42/3*7-2(23)\r\n" );
document.write( "\r\n" );
document.write( "Now since there is only one number inside that parentheses, \r\n" );

document.write( "\r\n" );
document.write( "42/3*7-2*23\r\n" );
document.write( "\r\n" );
document.write( "Now the highest order of operations that appears is multiplication\r\n" );

document.write( "\r\n" );
document.write( "The first multiplication or division that we come to going left to\r\n" );
document.write( "right is the division 42/3 so we do that and get 14.  We replace the\r\n" );

document.write( "\r\n" );
document.write( "14*7-2*23\r\n" );
document.write( "\r\n" );
document.write( "Now the first multiplication or division that we come to going left \r\n" );
document.write( "to right is the 14*7 so we do that and get 98.  We replace the\r\n" );
