How many ways can you get a sum of 1?
how many ways can you get a sum of 1?
Write the number 18 as the sum of two primes?
1 + 17 = 18 5 + 13 = 18 7 + 11 = 18
16 as sum of two primes?
16 = 1+15, 3+13, 5+11, 7+92,3,5,7,11,13 are primes < 1616 = 3+13 or 5+11
How would you write out the sum of twice n and 3 times m?
sum = 2n + 3m
How do you write The sum of m and 8?
m + 8
Write 100 as the sum of two primes in six different ways?
100 = 62 + 82 = 82 + 62 and there is no other way
Write 100 as the sum of two primes?
100 can be expressed as the sum of two primes in 6 different ways (ignoring order): 100 = 3+97 = 11+89 = 17+83 = 29+71 = 41+59 = 47+53
How many ways can you write 100 as a sum of 2 primes?
3 + 97 11 + 89 17 + 83 29 + 71 41 + 59 47 + 53 I think these are all of them.
How many ways can 24 be written as the sum of two different prime numbers?
Two, if the order of the primes is ignored.
Write the number 12 as the sum of two primes?
12=5+7
In how many ways can 24 be written as sum of two diffrent prime numbers?
How about: 17+7 = 24, 19+5 = 24 and 11+13 = 24 as three examples
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.
How can many different ways can you write fraction that has a numerator of 3 as a sum of fractions?
There are infinitely many ways.
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.
Is the sum of prime numbers cannot be a prime?
Not true. 2 + 3 = 5, where all three are primes. One of the primes in the sum must be 2, otherwise both primes would be odd and their sum would be even (and >2) and therefore not prime. Such primes: p and p+2 [3 and 5 in the above example] are known as twin primes and there are infiitely many twin primes.
What prime numbers add up to 92?
Write 92 as the sum of two primes
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.
