The sum of all prime numbers between 10 and 16 is 41.
The sum of the smallest and largest prime numbers within 10 is 7.
They are: 2+3+5+7 = 17
For a 2-digit prime number (which are all odd) to be the sum of two prime numbers, one of the prime numbers will have to be 2. That means the difference between the sum and the other addend will have to be 2. Prime numbers that differ by 2 are called twin primes. There are six pairs of 2-digit twin primes. Your numbers are 13, 19, 31, 43, 61 and 73.

11,13,17,19,23,29 = 112
The prime numbers between 40 and 60 are 41, 43, 47, 53 and 59. These sum to 243.
Prime numbers less than 10 = 2, 3, 5, 7The sum of prime numbers less than 10:= 2 + 3 + 5 + 7= 17
They are: 2+3+5+7 = 17
