false sometimes it contains 2 primes it always comes out to a prime number
No, you can apply any mathematical operation to a prime number.
false
Not always because as for example 2*19 = 38
You can divide 31 by any number. But because it is a prime number, the answer will always be a decimal.

The sum of any two prime numbers is not always a composite number. The sum of 2 and 11 is 13, and 13 is a prime number, not a composite number.

If you are asking if 11 is prime, yes it is a prime number. However, any number can be divided by any number technically speaking, it just doesn't always come out as an integer.
NO. The product of any two prime numbers are not always odd.Examples:2 x 3 = 62 x 5 = 102 x 11 = 22
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 evenThere ya go :)
The product of any number's prime factors will always be the number. The prime factors of 62 are 2 and 31 - the only number which can be produced by multiplying 2 and 31 is 62.
Because 2 is a prime number and 2 added to any other prime number will give an odd result.
Prime numbers, except 2, are always odd (they would not be prime if they were even cos they would be divisible by 2.) 1 less than any odd number must be an even number.
