public static void main(String[] args){
int num1 = 0;
int num2 = 0;
int num;
int user;
num1 = (int)(Math.random() * 9+1);
num2 = (int)(Math.random() * 9+1);
num = num1 * num2;
while(true){
// get answer from user
Scanner input = new Scanner(System.in);
System.out.println("How much is " + num1 + " TIMES " + num2 + "?");
user = input.nextInt();
if(user!= num){
System.out.println( "No. Please try again.");
}
else{
System.out.printf( "Very Good!");
}
