A composite number is a number which is not prime. All numbers are divided into the categories of either prime or composite (except for the number 1, which is neither). Examples of composite numbers are: 4,6,8,10 etc. All even numbers and square numbers are composite. There are, however, odd and non-square numbers that are composite as well, such as 15,21,27 and 55.

Infinity. There's an infinite number of place values, so you can create an infinite number of numbers that start with nine. Some of these will be prime, and since there is an infinite number of numbers starting with nine, there is an infinite number of prime numbers that start with 9 as well.

Type your answer here... well.. prime numbers and composite numbers are the opposite. prime number has 2 factors (1 and itself ) and a composite has more than 2 factors.
