4 public static void main(String[] args) {
5 int number1 = (int)(Math.random() * 10);
6 int number2 = (int)(Math.random() * 10);

8 // Create a Scanner
9 Scanner input = new Scanner(System.in);
10
11 System.out.print(
12 "What is " + number1 + " + " + number2 + "? ");
13 int answer = input.nextInt();
14
15 while (number1 + number2 != answer) {
16 System.out.print("Wrong answer. Try again. What is "
17 + number1 + " + " + number2 + "? ");
18 answer = input.nextInt();
19 }
