Except for 2 all other prime numbers are odd. Otherwise, they would be divisible by 2 (and thus not a Prime number). This does NOT mean that all odd numbers are prime, but that all prime numbers (aside from 2) are odd.

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".
What is the least odd prime number?
3 is the smallest odd prime number.
When you multiply two prime numbers you always get an odd number?
No. 2 times 3 is 6. Multiplying any number by 2 will make it even. Other than that, since all other prime numbers are odd, yes.No, because 2 is a prime number, and any prime number multiplied by 2 is even. However, for any product in which 2 is not a factor, it is odd by definition.
Which is the smallest odd prime number?
3 is the smallest odd prime number.
Is a prime number odd?
