The sum of my ones and tens digit is 10. My tens digit is greater than my ones digit. I am a prime number. What number am I?

  • math -

    Using your first two sentences, I see only the following possibilities
    91
    82
    73
    64
    of these only 73 is prime.

    I am assuming you wanted only a 2 digit number.

    but don't the following also fit all your conditions ?

    191,173,1873,1973,3491, .... ?
