As long as 2 is not one of the primes that you are adding, then I can guarantee that you will get a composite. 2 is the only even Prime number. Any time you add two odd numbers together, you will get an even number (which is not prime). So if you add them in pairs, you will have three even numbers, which added together result in an even number, so it is composite. If you throw in 2 as one of the primes that you're adding, then your result is odd, and I don't know what else to say about your result.
What else can I help you with?
Is prime number less that 9 is equivalent to composite numbers less than 12?
You may mean: 3 and 5 are prime numbers that add up to the composite number of 8
If you add a prime number to itself is the sum composite or prime?
Composite.
If you add a prime number to itself is the sum prime or composite?
Composite.
If you add a prime number to it self is the sum composite or prime?
When you add a prime number to itself, the result is always an even number greater than 2. For example, if you take the prime number 3 and add it to itself, you get 6, which is composite. Since the only even prime number is 2, adding any prime number greater than 2 to itself will always yield a composite number.
What 3 prime numbers make 99?
The three prime numbers that add up to 99 are 3, 5, and 91. However, 91 is not a prime number, so a combination of prime numbers that sums to 99 doesn't exist. The only way to express 99 as a sum of prime numbers would involve at least one composite number.
Is the addition of two composite numbers also a composite number?
Not necessarily. For example 15 and 16 are composite numbers. They add to 31, which is a prime number. Similarly, the composite numbers 20 and 21 add up to 41, which is a prime number.
If you add a prime number to itself is the the sum composite or prime?
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
What kind of number do you get when you add 2 prime numbers?
composite
Is prime number less that 9 is equivalent to composite numbers less than 12?
You may mean: 3 and 5 are prime numbers that add up to the composite number of 8
How many district composite numbers can be formed by adding 2 of the first prime numbers?
The first two prime numbers add up to another prime number.
If you add a prime number to itself is the sum composite or prime?
Composite.
If you add a prime number to itself is the sum prime or composite?
Composite.
Are prime numbers closed under addition?
no, not all prime numbers are closed under addition. why? because, when you add 2 prime numbers you will not always get a prime number. example: 5+3= 8 5 and 3 are prime numbers but their sum is 8 which is a composite number..
If you add a prime number to it self is the sum composite or prime?
When you add a prime number to itself, the result is always an even number greater than 2. For example, if you take the prime number 3 and add it to itself, you get 6, which is composite. Since the only even prime number is 2, adding any prime number greater than 2 to itself will always yield a composite number.
Are composite numbers closed under addition?
No, they are not. You can add two composite numbers, 15 and 14 for example, and get a sum, 29, that is prime.
What are all the composite numbers between 30-40 that have prime factors that add up to 12?
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
What 3 prime numbers make 99?
The three prime numbers that add up to 99 are 3, 5, and 91. However, 91 is not a prime number, so a combination of prime numbers that sums to 99 doesn't exist. The only way to express 99 as a sum of prime numbers would involve at least one composite number.
