import java.util.*;


class App {


	public static void main(String[] args) {
		Scanner keyboard = new Scanner(System.in);
		int n = -1;
		while (n < 1) {
			System.out.print("Enter the integer number: ");
			n = keyboard.nextInt();
			if (n < 1) {
				System.out.println("Wrong the integer number! Try again. ");
			}
		}


		for (int i = 1; i <= 12; ++i) {
			System.out.println(n + " * " + i + " = " + n * i);
		}
		keyboard.close();
	}
