using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("3 * 7 = {0}", multiply(3, 7));
            Console.WriteLine("3 * 0 = {0}", multiply(3, 0));
            Console.WriteLine("0 * 3 = {0}", multiply(0, 3));
            Console.WriteLine("3 * -5 = {0}", multiply(3, -5));
            Console.WriteLine("-3 * 6 = {0}", multiply(-3, 6));
        }
        static int multiply(int x, int y)
        {
            if (y > 0)
                return (x + multiply(x, y - 1));

            if (y < 0)
                return -multiply(x, -y);

            return 0;
        }
    }
}

/*
run:
    
3 * 7 = 21
3 * 0 = 0
0 * 3 = 0
3 * -5 = -15
-3 * 6 = -18
       
*/
