:rolleyes: I need some one to define prime numbers for me

A full definition, I am trying to write a program to determine wether a number is prime, print all prime numbers in a specific range ... e.t.c so i need a full definition of prime numbers, i know prime numbers are divisible only by one and theirselves, and when i remove all odd and even numbers from a set of numbers, i will be left with prime numbers.....

i think if i know more about prime numbers i can come up with something more.....

so i need someone to help
