//5!= 5*4*3*2*1=120 = 5 * 4!
//1!=1
//0!=1 //IMPORTANT

//A LITTLE IMPORTANT... write method that takes base as paramneter and power as parameter and return base ^ power 2 ,3 =8  4,2 =16
//write method named isprime(اولي) and determine if it is prime or not
//that takes inetger prime number divisible by one and itself only , method it will return true if number is prime otherwise it will false
/*
//A LITTLE IMPORTANT... write method named checkrangeprime that takes two intgere and print if each number is prime or not prime in this range

//Question One (Random):
//1. Write a method calculateRightAnswer that takes two integers and returns their summation.
//2. Write a method checkAnswer that takes three integers. The method should check whether 
//the summation of the first two integers equals the third. If so, the method should return 
//(true), otherwise, the method should return (false).
// Hint: use the calculateRightAnswer method.
//3. Implement the main() method as follows:
//a. Generate two integer values randomly in the range [1-10].
