    Smile Real Numbers and Their Relationships

    What relationships can we find between composite and even numbers and also odd numbers and prime numbers?

    To me:

    composite numbers = even numbers

    AND

    odd numbers = prime numbers.

    What is the connection and difference between the numbers mentioned here?

    All evens (except 2) are composite, but not all composite are even.

    All primes (except 2) are odd, but not all odds are primes.
