Please help me with the task: Calculator.

Hello, I’m working on this task:

Write a program that first waits for the user to input two integers, A and B, one after the other, from the console. Then the user should input the operation “add” or “multiply”. If the user inputs “add”, output the sum of A and B. If the user answers “multiply”, output the multiplication product of A and B. For example:
>12
>3
>add
15

Here is my code:


namespace Booleans
{
   public class ConsoleReadLine
   {
       public static void Main(string[] args)
       {
           string aString = Console.ReadLine();
           string bString = Console.ReadLine();

           int a = int.Parse(aString);
           int b = int.Parse(bString);

           string operation = Console.ReadLine();

           Console.WriteLine(a);
           Console.WriteLine(b);
           Console.WriteLine(operation);

           if(operation == "add")
           {
               Console.WriteLine(a + b);
           }
           else(operation == "multiply")
           {
               Console.WriteLine(a * b);
           }
       }
   }
}


Can anyone please help me to solve it?

        string aString = Console.ReadLine();
        string bString = Console.ReadLine();

        int a = int.Parse(aString);
        int b = int.Parse(bString);

        string operation = Console.ReadLine();

        

        if (operation == "add")
        {
            var res = a + b;
            Console.WriteLine(res);
        }
        else if (operation == "multiply")
        {
            var res = a * b;
            Console.WriteLine(res);
        }
