1/3
The prime number less than 10 that, when added to either 10 or 20, results in a prime number is 3. When you add 10 to 3, you get 13, which is a prime number. Similarly, when you add 20 to 3, you get 23, which is also a prime number.
Prime number
The sum of two prime numbers will be composite unless one of the prime numbers is 2.
Find the prime factorization. Identify the distinct prime factors. Add them up.
No. It is also divisible by 3, as you will see if you add the digits of the number together.
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.
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
2. 2 + 3 = 5 Or if you mean like add 3 to the prime number, then add that to the prime? 2 still works!! 2: 2 + 3 = 5. 5 + 2 = 7
It is: 11 because 1+1 = 2 which is the smallest prime number
Composite.
Composite.
The prime number less than 10 that, when added to either 10 or 20, results in a prime number is 3. When you add 10 to 3, you get 13, which is a prime number. Similarly, when you add 20 to 3, you get 23, which is also a prime number.
Prime number
You can get another prime (only if one of the numbers added is 2), for example, 101 + 2 = 103. If you add together two odd prime numbers, you will get an even number, which will not be a prime number. (An even number is a number that is divisible by 2; if such a number is greater than 2, it is not a prime number.)
7 x 13
3
When you add two or more prime numbers you will only end up with a whole number and not a decimal number.
