 @using (Html.BeginForm()) {  
    
  
        
  
            
 First Number

 } 

and now we are going for a method in controller

[HttpPost]  
public ActionResult Calculat(string firstNumber, string secondNumber, string Cal) {  
    int a = Convert.ToInt32(firstNumber);  
    int b = Convert.ToInt32(secondNumber);  
    int c = 0;  
    switch (Cal) {  
        case "Add":  
            c = a + b;  
            break;  
        case "Sub":  
            c = a - b;  
            break;  
        case "Mul":  
            c = a * b;  
            break;  
        case "Div":  
            c = a / b;  
            break;  
    }  
    ViewBag.Result = c;  
    return View();  
}
