What is the sum of the primes below 10?
They add up to 17
What is the sum of the prime numbers below 10?
1, 2, 3, 5, 7 are the primes under 10. Those add up to 18.
What 2 odd primes equal the sum of 10?
The prime numbers 3 an 7 are both odd and sum to 10.
What are the odd numbers between 10 and 30 as the sum of three odd primes?
10
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 are the three odd primes with the sum of 14?
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
What is the first prime which can be the some of free different primes?
Are you asking The first prime that is the sum of three primes? I'll help. 2,3,5 are the first 3. the sum is 10. Not prime. now try 3,5,7. 15. Not prime. 5,7,11. 5,7,11 work, the sum is 23, which is a prime, not divisible by 2,3,4,5,6,7,8,9, so on. So the Three Primes are 5 7 11. The sum is 23.
What is the sum of all primes?
Infinity.
Is the sum of prime numbers cannot be a prime?
Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.
Can a product of primes be split into sum of three products of primes?
Sure. All composite numbers can be written as a product of primes. It shouldn't be tough to find a composite number that's the sum of three other composite numbers. Let's try 30. 2 x 3 x 5 = 30 Product of primes, check. 6 (2 x 3) + 10 (2 x 5) + 14 (2 x 7) = 30 Sum of three products of primes, check.
What pair of twin primes have a sum of 84?
The twin primes 41 + 43 = 84.
What are three odd primes with sum of 30?
This question cannot be answered because three odd primes always have an odd number for their sum.
