Associative
Their product
They are integers. They are below 26 They are positive numbers They are above 8 If they are multiplied by 2 the product is an even number They have no common factor They are square numbers
There is no specific name. For example, (-2)*(-3) = +6 but there is no special name for -2 and -3.
You probably could figure this one out: it's ZERO.
Yes, it is always. Assume temporarily that the product of two prime numbers is not always composite. This implies that that at least one product of prime numbers is also prime. Now, say two different prime numbers p and q, when multiplied, equal r. If r is a prime number, then r's only positive factors are 1 and r. But 1 is not a prime number. This contradicts that both p and q are prime (because either p or q MUST be 1). Therefore, the product of two prime numbers is always composite.
The way in which numbers are grouped when added or multiplied does not change the sum or product.
This is called the "commutative" property.

if 2 positive numbers are multiplied, then the product is positive. if 2 negative numbers are multiplied, the product is positive. if a positive and a negative number are multiplied, the product is negative.
That is due to the Abelian, or commutative property of multiplication over the set of numbers.
