Can you find two consecutive integers whose sum is -31?
The numbers are -16 and -15.
What two numbers have a sum of 16 and a difference of 14?
15 + 1 = 16, and 15 - 1 = 14, so the two numbers are 15 and 1.
What even number is not the sum of two primes?
16
Which two primes have a sum of 16 and a product of 55?
5 & 11 !
How many of the prime numbers between 10 and 20 can be written as the sum of two primes?
All prime numbers greater than 2 are odd numbers. For an odd prime to be written as the sum of two primes, one of the primes must be 2 because two odd primes will produce an even sum. 11 cannot be written as the sum of two primes. 13 = 2 + 11. 17 cannot be written as the sum of two primes. 19 = 2 + 17.
The sum of two odd number is?
The sum of two odd primes is always an even answer or number.
What is 98 as the sum of two primes?
It is: 19+79 = 98
What is the smallest prime number that is the sum of two primes?
5
What is 15 as the sum of two primes?
It is: 2+13 = 15
What are the three odd primes with the sum of 14?
There are not three odd primes with the sum of 14. The sum of three odd primes will be an odd number.
Is the sum of two prime numbers always a prime numer?
It is not. Of the infinitely many primes only one (the number 2) is even, the rest are all odd. The sum of any two primes other than 2 is even and therefore not a prime. If one of the primes in the sum is 2 then the sum is a prime only if the other is the lower of a pair of twin primes. So, while it is possible, it is certainly more likely that the sum is a composite.
What is the only prime number that is the sum and difference of two primes?
5
