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.

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 prime or composite?
Composite.
If you add a prime number to itself is the sum composite or prime?
Composite.
What three numbers add up to a prime number?
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
Is the number 4 a composite number?
Yes it is, the numbers that can add up to 4 are 1, 2 and 4. A prime number is a number that can only go to itself and 1 evenly, composite have atleast 1 other number that goes into it perfectly. (that's what she said)
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 prime or composite?
Composite.
If you add a prime number to itself is the sum composite or prime?
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..
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.
If you add a prime number and a prime number will the sum always be prime?
If you add two prime numbers that are odd numbers, the sum will be an even number. Because even numbers are divisible by 2, no even number greater than 2 is a prime number. Here are some examples:3 + 3 = 6 which is an even number and thus not a prime number5 + 7 = 12 which is an even number and thus not a prime number11 + 13 = 24 which is an even number and thus not a prime number19 + 41 = 60 which is an even number and thus not a prime numberIf you add a prime number that is odd to the only even prime number (2), you will have an odd number. This odd number might be prime or might be composite. Here are some examples:2 + 3 = 5 which is a prime number2 + 7 = 9 which is a composite number2 + 23 = 25 which is a composite number2 + 41 = 43 which is a prime numberQuestion what is zero = composite0 x 1 = 00 x 4 = 00 x 16 = 00 x 64 = 0
Is 441 a prime or composite number?
Any number whose digits add up to 9 or a multiple of 9 is divisible by 9. Since the numbers' digits also add up to a multiple of 3, 441 is also divisible by 3.A complete list of all of the positive integer factors of the number is:1, 3, 7, 9, 21, 49, 63, 147, 441441 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
