The prime numbers of: 23 plus 7 = 30 Also, 11 + 19 = 30 and 13 + 17 = 30
They will be negative numbers as for example -5+(-7) = -12
7 & 9
2, 7, and 89 are three prime numbers whose sum is 98.
The two prime numbers that add up to 19 are 7 and 12. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves. In this case, 7 and 12 are not prime numbers, and there are no two prime numbers that add up to 19.
The sum of any two prime numbers may or may not be prime. The sum of the two prime numbers 2 and 3 is the prime number 5, and the sum of the two prime numbers 5 and 7 is the composite number 12.
The sum of 7 and 19 is 26.
I assume you are asking the question "what two prime numbers sum to 44". There may be other pairs of prime numbers that sum to 44, but 37 and 7 are both primes and their sum = 44.
There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
5 and 7
7+3
5 = 2+3 = 7-2
Yes, 7 and 7.
If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)
13 and 5 11 and 7
They are: 5+7 = 12
41 and 7 43 and 5
