What are the three smallest primes whose sum is a prime number?
3, 5 and 11
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.
Prime that is the sum and difference of two primes?
5 is the answer 2+3=5 7-2=5
The sum of the primes below 10?
It is: 2+3+5+7 = 17
What is the only prime that is the sum and diffence of two other primes?
2 + 3 = 5 7 - 2 = 5 The number is 5.
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.
Prime number that is the sum and difference between two primes?
3 + 2 = 5 = 7 - 2
The only prime that is the sum and differences of two primes?
52+3=5 and 7-2=5
What 2 integers whose sum is 2 and whose difference is 8?

What are two prime numbers whose difference is 2?
They are known as twin primes. 3 and 5 5 and 7
What prime number less than 20 can be written as a sum of differrent primes?
2 + 3 = 5
What is the smallest prime number that is the sum of two primes?
