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

73?

10 + 0

To find the number that satisfies these conditions, we need to go through all the prime numbers and check which ones meet the given criteria: a sum of ones and tens digits equal to 10, and the tens digit being greater than the ones digit.

Starting with the prime numbers, such as 2, 3, 5, 7, 11, 13, 17, and so on, we can see that 17 fits the given conditions. The sum of the ones and tens digits (7 + 1) equals 8, and the tens digit (7) is greater than the ones digit (1). Therefore, the number that satisfies all the conditions you mentioned is 17.
