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.
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
Well, isn't that a happy little math question! The two prime numbers that add up to 91 are 89 and 2. Remember, prime numbers are like little gems in the mathematical world, shining brightly with their unique properties. Keep exploring and discovering the beauty of numbers, my friend!
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.
