What 2 prime numbers add to make 1.32?

When you add two or more prime numbers you will only end up with a whole number and not a decimal number.


What 2 prime numbers add together to make 91?

Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.

Can you add two prime numbers to make another prime number?

Yes as for example 2+5 = 7


What two prime numbers add together to make 97?

The only way two prime numbers add up to an odd number is if one of them is 2. Since 95 isn't prime, there is no solution.


What two prime numbers add up to 144?

Split the number in half and make an equation adding the two together to make the desired amount. Unless the number that is half the total is prime, adjust the first number down by an amount to make it a prime number, then adjust the second one up by an equal amount and check whether it is also a prime number. If the second number is also a prime number, you have found two prime numbers that equal the desired amount. If not, adjust the first number down to another prime number, repeating the procedure above until you have two prime numbers.If you split 144 in half, the result is 72. Take the equation 72 + 72 = 144. Since 71 is prime, adjust the first number down by 1 and the second number up by 1 to get 71 + 73 = 144. Since 73 is prime, too, you now have two prime numbers that add up to 144.


If you add two prime numbers together what do you get?

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.)


What even number cannot be formed by two prime numbers?

You can not add two positive prime numbers and get zero.


What is a prime number between 30 and 40 that when you add the two factors together you get 10?

This question doesn't quite make sense; a prime number has no factors.If you meant a prime whose digits sum to 10 it is 37.


Does two prime numbers always add up to an even number?

No, they do not. If one of the prime numbers is 2, you will have an odd number.


Two prime numbers that add to make the number 50?

What two prime numbers make 95?

To start, 95 is a multiple of 5 (which is prime). We know this from the one's digit (either 0 or 5).So 95 /5 = 19, which is prime. So 5 x 19 = 95.Multiplication is the only way, not addition. No two prime numbers can add to make an odd number, by the way. The only even prime number is 2, so all other primes are odd. Add any two odd numbers will result in an even number.So if 2 can be added to a number to get 95, the other number is 93, which is divisible by 3, and is not prime.
