Set u = ones digit
\n" ); document.write( " t = tens digit
\n" ); document.write( "t*10 + u >= 30
\n" ); document.write( "t*10 + u <= 60
\n" ); document.write( "u = t-3\r
\n" ); document.write( "\n" ); document.write( "Possible tens digits are 3 4 and 5, not 6 since 60 is not prime.
\n" ); document.write( "2 digit prime numbers beginning with 3
\n" ); document.write( "31 , 37
\n" ); document.write( "2 digit prime numbers beginning with 4
\n" ); document.write( "41 , 43 , 47
\n" ); document.write( "2 digit prime numbers beginning with 5
\n" ); document.write( "51 , 53 , 57\r
\n" ); document.write( "\n" ); document.write( "41 is the only number that is prime between 30 and 60
\n" ); document.write( "and the tens digit is 3 more than the units digit.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
