operator overloading simple example

The operator overloading allows the operators e.g., +, -, /, *, etc to operate on operands of non primitive/basic data types, such as int, float, double, etc. The following example explains operator overloading:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication8
{

   class Money
    {
        public int money;

        public int MoneySum
        {
        get
            {
            return money;
            }
        }

        public Money()
        {

        }
        public Money(int money)
        {
            this.money = money;
        }

        public static Money operator + (Money m1, Money m2)
        {
            Money ans = new Money();
            ans.money = m1.money + m2.money;
            return ans;
        }

        public static Money operator -(Money m1, Money m2)
        {
            Money ans = new Money();
            ans.money = m1.money - m2.money;
            return ans;
        }

        public static Money operator *(Money m1, Money m2)
        {
            Money ans = new Money();
            ans.money = m1.money * m2.money;
            return ans;
        }

    }

    class Program
    {     

        static void Main(string[] args)
        {

            Money m1 = new Money(1);
            Money m2 = new Money(2);
            Money m3 = new Money(3);
            Money m4 = new Money(4);
            Money m5 = new Money(5);

            Money ans = m1 + m2 - m3 * m4 - m5;
            
            Console.WriteLine(ans.MoneySum);
            

         
        }

    }
}
