What types of numbers are there besides prime and composite?
There are integers such as 0 and 1. Then there are non-integer rational and real numbers.
What are prime numbers used for in the real world?
cryptography
What composite number is equal to the product of the first four prime numbers?
Sure thing, honey. The first four prime numbers are 2, 3, 5, and 7. Multiply those bad boys together and you get 210. And wouldn't you know it, 210 is a composite number because it can be divided by numbers other than 1 and itself. Math can be a real hoot sometimes, can't it?
What are non-zero real numbers?
Non-Zero Real Numbers are infact complex conjugate numbers. They are negative prime numbers.
Are their more prime numbers than normal numbers?
No, there are more normal numbers than prime numbers. Since 2, 3, 5, 13, and 19 are some examples of prime numbers, those only seem to be a few. Remember, numbers can stretch as far as someone wants, so 1,000 isn't a prime number, since you can have 250 and 4 to multiply into it, and 250 and 4 aren't prime numbers. Since the number scale can go on forever, there are more real numbers than prime numbers.
