Is it true that if you add any 2 prime numbers you get an even number?

Yes, think about it...
you can't have an even Prime number(except 2), as it would be divisible by two..
So all primes must be odd, and odd + an odd always = an even
There ya go :)

Could prime numbers can never be even numbers?
Not quite true . . . the number '2' is a prime number. All the rest of the even numbers cannot be prime because they always can be divided by 2.
Is it true or false that only odd numbers are prime numbers And why?
False because 2 is an even number which is also a prime number.
Is it true that all the prime numbers are odd?
That is false. Two is a prime number and two is even.
The product of two prime numbers is never an even number?
Not always true because 2 times 13 = 26 which is an even number
True or false two is the only even number that is prime?
True, 2 is the only known even prime number.

Is it true that all the prime numbers are odd?
That is false. Two is a prime number and two is even.
No even numbers are prime numbers true or false?
2 is prime
What is true about prime number?
Here are some facts about prime numbers:1. Prime numbers have exactly two factors - 1 and the prime number itself.2. The only even number that is prime is 2.3. There are an infinite number of prime numbers.4. Every number can be uniquely represented as a prime number or a product of prime numbers.
Is the only even prime number is 2 t or f?
Yes, it is true that 2 is the only even prime number. All even numbers are evenly divisible by 2 (that is the definition of an even number). The number 2 is also divisible by 2, however, prime numbers, like all numbers, are evenly divisible by themselves, so that does not disqualify 2 from being a prime number.
Is it true that the sum of two prime numbers is always an even number?
Not quite.When two prime numbers of 3 and higher are added together, the result is always even, because all such prime numbers are odd numbers, and when two odd numbers are added together, the result is always an even number.However 2 is a prime number, and 2 is also an even number. Adding 2 (an even number) to a different prime number (an odd number) will always yield an odd number.Only if you don't include "2".
Is it true that prime numbers can never be even numbers?
No, 2 is prime.
Is it true or false that two composite numbers are relatively prime and explain?
Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.
Is it true that if you add 2 prime numbers you always get an even number?
As long as one of the numbers isn't 2, adding any two prime numbers results in an even number. Why? 1.) Adding any two odd numbers gives an even number, 2.) adding an odd and an even gives an odd, and 3.) all primes are odd, except for 2.
The product of two prime numbers is never an even number?
Not always true because 2 times 13 = 26 which is an even number
True or false two is the only even number that is prime?
True, 2 is the only known even prime number.
