Any prime number greater than 10 is an odd number but cannot end in 5 as this makes it divisible by 5. Therefore the ones digit of any prime number greater than 10 must be 1, 3, 7 or 9.
The prime number between 20 and 30 whose ones digit is 7 greater than its tens digit is 23. The tens digit is 2, and the ones digit is 3, which is 7 greater than 2. Additionally, 23 is a prime number because it is only divisible by 1 and itself, with no other factors.
There is no single digit number greater than 9. After 9 is 10, which is a double-digit number.
When its digital root is 9 (divisible by 9) and it is even (divisible by 2). The digital root of a number is calculated by adding up all the digits in a number. If the answer is greater than 9, then repeat until you get an answer that is a single digit.
