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 prime number less than 20 can be written as a sum of differrent primes?
2 + 3 = 5
What is the sum of all primes between 20 and 60?

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!
Which of the following cannot yield an integer when divided by 10?
All of these could yield an integer when divided by 10. 1. sum of two integers: ( 10 + 10)/10 = 2 2. integer less than 10: -20 < 10 and -20/10 = -2 3. product of 2 primes: 2 and 5 are primes and 2*5/10 = 1 4. sum of three consecutive integers ; (9+10 + 11) /10 3

What is addends for the sum of 50?
Addends are the numbers that are combined to create a sum. For the sum of 50, any pair of numbers that, when added together, equals 50 can be considered addends. For example, 20 and 30, or 25 and 25 are both sets of addends that sum to 50. There are infinitely many combinations of addends that can achieve this sum.

How many sets of twenty in 700?
To find out how many sets of twenty are in 700, you divide 700 by 20. This calculation gives you 700 ÷ 20 = 35. Therefore, there are 35 sets of twenty in 700.
