What numbers have 5 as a factor?
5 is a factor of any whole number ending in 5; it is also a factor of any whole number of 2 or more digits ending in zero.
Is negative 43 an integer?
Yes, negative 43 is an integer. An integer is a whole number that can be positive, negative, or zero. In this case, negative 43 is a whole number that is less than zero, making it an integer.
What whole number are neither prime or composite?
One is neither a prime nor a composite number. A prime number is one with exactly two positive divisors, itself and one. One has only one positive divisor which is itself so it is not prime. Furthermore, it cannot be written as a product of two factors, neither of which is itself. This tells us that one is also not composite. The other number which is neither prime not composite is Zero which has an infinite number of divisors since any nonzero whole number divides zero. Zero cannot be be written as a product of two factors, neither of which is itself, so zero is also not composite.

Why is zero not an even prime number?
Because one does not go into zero. A prime number is any number that has only one and itself as factors. Since one goes in to zero no times, the number is not prime.
