What three numbers add up to a prime number?
if you mean what three prime numbers add up to a prime number then the answer is : 5 + 7 + 11 = 23
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.
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.
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.)
If you add or subtract using only prime numbers is the answer always a prime number?
No, as all prime numbers are odd, excluding 2, and when you add two odd numbers you get an even number. This even number can't be a prime number as it will be divisible by 2. 101 and 31 are both prime, but 101+31 is 132.
