:) Prime Numbers

Take a prime number for example, 23. To find out if it is happy you have to start off by separating the digits, 2,3. Then square the digits and add them together: 4+9=13. Then go over this again and you will get 10. If you separate those digits it will be (1*1)+(0*0)=1. And there you have it, a happy prime number!! See if you can find any other happy prime numbers and reply to this post!!
