document.write( "Consider all natural numbers from 1 to 101, inclusive.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Their amount is 101.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this amount, exclude all even natural numbers from 1 to 100 ---  their amount is   = 50.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The difference  101 - 50 = 51  is your answer.\r\n" );
