Try this: using System; class Program { static void Main() { int x y; while(true) { Console.Write(Enter first non-negative integer : ); bool isValid = int.TryParse(Console.ReadLine() out x); if (!isValid || x { Console.WriteLine(Invalid try again); } else { break; } } while(true) { Console.Write(Enter second non-negative integer : ); bool isValid = int.TryParse(Console.ReadLine() out y); if (!isValid || y { Console.WriteLine(Invalid try again); } else { break; } } int answer; Console.WriteLine(); Console.Write({0} + {1} =  x y); int.TryParse(Console.ReadLine() out answer); if (answer == x + y) { Console.WriteLine(Correct); } else { Console.WriteLine(Incorrect); } Console.WriteLine(); Console.Write({0} - {1} =  x y); int.TryParse(Console.ReadLine() out answer); if (answer == x - y) { Console.WriteLine(Correct); } else { Console.WriteLine(Incorrect); } Console.WriteLine(); Console.Write({0} x {1} =  x y); int.TryParse(Console.ReadLine() out answer); if (answer == x * y) { Console.WriteLine(Correct); } else { Console.WriteLine(Incorrect); } Console.ReadKey(); } }
