Try this: using System; class Test { static void Main() { int a b; Console.Write(Enter first number : ); int.TryParse(Console.ReadLine() out a); Console.Write(Enter second number : ); int.TryParse(Console.ReadLine() out b); Console.WriteLine({0} x {1} = {2} a b Multiply(a b)); Console.ReadKey(); } static int Multiply(int a int b) { if(a == 0 || b == 0) return 0; int c = Math.Abs(a); int d = Math.Abs(b); int result = 0; for(int i = 1; i if ((a 0) || (a > 0 && b return result; } }
