"Write a function that determines if a number is prime or not. The function should accept a number and return true if the number is prime or false if the number is not prime. A prime number is a number that is divisible only by itself and one. For example, 10 is NOT prime since it si divisible by 2 and 5. The number 5 IS prime since it is divisible by 1 and 5 only."
