Solution

using System;
public class BasicCalculatorSwitch
{
    public static void Main(string[] args)
    {
        int a = Convert.ToInt32(Console.ReadLine());
        char operation = Convert.ToChar(Console.ReadLine());
        int b = Convert.ToInt32(Console.ReadLine());

        switch (operation)
        {
            case '+':
                Console.WriteLine("{0}+{1}= {2}",a,b,a+b);
                break;
            case '-':
                Console.WriteLine("{0}-{1}= {2}",a,b,a-b);
                break;
            case 'x':
            case '*':
                Console.WriteLine("{0}x{1}= {2}",a,b,a*b);
                break;
            case '/':
                Console.WriteLine("{0}/{1}= {2}",a,b,a/b);
                break;
            default:
                Console.WriteLine("Unrecognized character");
                break;
        }
