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.
What is the sum of all prime numbers between 10 and 20?
Oh, what a delightful question! Let's take a moment to appreciate the beauty of prime numbers. The prime numbers between 10 and 20 are 11, 13, 17, and 19. When we add them together with a gentle brushstroke of mathematics, we get a sum of 60. Happy little primes indeed!

What is the sum of all prime numbers between 20 and 40?
To find the sum of all prime numbers between 20 and 40, we first list out the prime numbers in that range: 23, 29, 31, 37. Then, we simply add them together: 23 + 29 + 31 + 37 = 120. Therefore, the sum of all prime numbers between 20 and 40 is 120.
