The sum of my ones digit and tens digit is 10.
\n" ); document.write( "

\r\n" );
document.write( "So it has to be one of these nine:\r\n" );
document.write( "\r\n" );
document.write( "19\r\n" );
document.write( "28\r\n" );
document.write( "37\r\n" );
document.write( "46\r\n" );
document.write( "55\r\n" );
document.write( "64\r\n" );
document.write( "73\r\n" );
document.write( "82\r\n" );
document.write( "91\r\n" );
document.write( "

\n" ); document.write( "My tens digit is less than my ones digit
\n" ); document.write( "

\r\n" );
document.write( "That narrows it down to these four:\r\n" );
document.write( "\r\n" );
document.write( "19\r\n" );
document.write( "28\r\n" );
document.write( "37\r\n" );
document.write( "46\r\n" );
document.write( "

\n" ); document.write( "and both my digits are prime.
\n" ); document.write( "

\r\n" );
document.write( "That narrows it down to 37\r\n" );
document.write( "

\n" ); document.write( "I am a prime number.
\n" ); document.write( "

\r\n" );
document.write( "Indeed, 37 is a prime number.\r\n" );
document.write( "

\n" ); document.write( "What number am I?
\n" ); document.write( "

\r\n" );
document.write( "37.\r\n" );
