What is the sum of prime numbers between 1 and 15?
The prime numbers between 1 and 15 are 2, 3, 5, 7, 11, and 13. To find the sum, you simply add these numbers together: 2 + 3 + 5 + 7 + 11 + 13 = 41. Therefore, the sum of prime numbers between 1 and 15 is 41.

How many even numbers are there between 10 and 30?
If you are including 10 and 30 there are 11 even numbers. If you are not counting 10 and 30 there are 9 even numbers between 10 and 30.

Including 11 they are: 11+13+17+19 = 60
What is the sum of all odd numbers between 9 and 15?
To find the sum of all odd numbers between 9 and 15, we first identify the odd numbers between these two values, which are 9, 11, 13, and 15. Next, we add these numbers together: 9 + 11 + 13 + 15 = 48. Therefore, the sum of all odd numbers between 9 and 15 is 48.
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
